Abstract
High-spin states in molecular systems hold significant interest for applications ranging from optoelectronics to quantum technologies. Spin states generated in intramolecular singlet fission are of particular relevance, yet the mechanisms controlling triplet-pair formation are not fully understood – especially the involvement of quintet states in luminescence at room temperature remains experimentally elusive. Here, we investigate high-spin state formation and emission in dimers and trimers comprising multiple diphenylhexatriene units. We demonstrate the formation of pure quintet states in all these oligomers, with quintet-mediated emission dominating delayed fluorescence up to room temperature. By distinguishing between the formation of weakly exchange-coupled triplet pairs and triplet excitons generated by intersystem crossing, we identify the methylated trimer as the only oligomer exhibiting exclusively the desired singlet fission route. These findings establish quintet-mediated delayed emission as a distinct spin-selective pathway and show how molecular structure directs high-spin formation, opening opportunities for room-temperature molecular quantum technologies.

Introduction
Molecular high-spin states present a diverse platform for organic optoelectronics and quantum technologies that involve complex processes requiring transition between different spin states1–4. One key application is singlet fission (SF), a fast, spin-conserving photophysical process converting singlet excitons rapidly into spin-correlated triplet pairs, before these dissociate into free triplets1,5. This principle has a significant potential impact on enhancing photovoltaic efficiency as photocurrent generation occurs from each triplet state6,7. Additionally, the formation of quintet states emerges as a critical aspect of the fission process, offering potential applications beyond photovoltaics, such as in quantum computing and spintronics8,9.

Whilst intermolecular SF has been extensively studied, we focus on intramolecular singlet fission (iSF), where molecular structures can be tuned to control the rates and generation of triplet pairs10–15. Recent literature has primarily explored iSF in dimers, for instance of pentacene16,17 and tetracene18–20, with only a few recent reports extending to trimer studies, which often exhibit distinct SF behaviour21,22. While these studies have provided insight into structural control and triplet dissociation, key questions remain regarding the formation and emissive pathways of high-spin states: (1) How do chromophore number and arrangement affect triplet pair separation and suppression of competing intersystem crossing (ISC)? (2) Do the high-spin states, particular the quintet states, participate in emission?

Previous studies have shown the importance of quintet formation and their spin dynamics in singlet fission systems, for instance in crystals, tetracene oligomers23 and metal-organic frameworks8, where conformational modulation of exchange interactions was linked to triplet pair dissociation and spin coherence. However, these works did not report optical spin readout, notably, room-temperature emission mediated by quintet states has not been addressed. This leaves a critical gap in understanding how high-spin states function as radiative intermediates and how they could be harnessed for spin-based technologies.

The magnetic field effect (MFE) on photoluminescence (PL) is a valuable technique to reveal spin-sensitive emission behaviours and even exchange interaction at higher fields24. However, it relies on passive field-induced perturbation of spin levels and is unable to distinguish the exact states involved. Optically detected magnetic resonance (ODMR) allows direct microwave-driven manipulation of spin sublevels, enabling a precise optical readout of the participating high-spin states. ODMR studies of SF materials have so far been limited to low temperatures or crystalline samples. To our knowledge, no report has demonstrated room-temperature ODMR detection of quintet-mediated emission in iSF systems or generally in molecular systems.

Here, we investigate diphenylhexatriene (DPH)-based oligomers to identify structural factors that govern quintet formation and reveal their contribution to PL. Next to a directly linked dimer (DPH)2 and trimer (DPH)3, we introduce a methylated trimer Me-(DPH)3 in this study. We focus particularly on the role of quintet-mediated delayed emission, as well as aiming to discriminate between formation of weakly-coupled triplet pairs and the formation of triplet excitons by ISC. Our previous work showed that these materials support triplet pair generation25, but the detailed spin-state formation and especially emission pathways, addressable by magnetic resonance techniques, remained unrevealed. By introducing methyl substitution to control molecular planarity26, we examine how structure influences the formation and emission of quintet and triplet states. Our goal is to identify molecules that can effectively emit via quintet states up to room temperatures, as well as suppress efficiency-limiting pathways as ISC, to optimize materials for both energy conversion and quantum technology applications.

We address these questions with a comprehensive set of advanced spin-sensitive optical and magnetic resonance techniques, combining transient electron paramagnetic resonance (trEPR), ODMR, MFE, and transient absorption (TA) to map the formation and emission of states with different spin multiplicities. The unique complementarity of these techniques is further discussed in Supplementary Note 3. In contrast to previous studies, this approach directly resolves the generation of quintet and triplet-pair states and provides clear experimental evidence for quintet-mediated emission.

In this study, we show that quintet states are generated across all studied oligomers and provide an optical readout pathway via ODMR up to room temperature, confirming their emissive character and long-lived nature in delayed fluorescence. Moreover, we distinguish between triplet multiplication via SF and triplet generation via ISC, and show that Me-(DPH)3 predominantly exhibits SF-derived triplet formation above 80K, with ISC contributions emerging only at lower temperatures. These findings establish DPH-based oligomers as model systems for understanding and exploiting quintet-mediated emission in high-spin molecular materials relevant to energy conversion and quantum photonics.

Results
Probing high-spin state formation by electron paramagnetic resonance
Figure 1a illustrates the molecular structures and corresponding trEPR measurements for the three oligomers studied to investigate the formation of triplet states and higher spin multiplicity pair states. As in our previous reports, (DPH)2 and (DPH)3 consist of two or three directly connected DPH chromophores, with terminal 2′-ethylhexyl groups (DEH) to aid solubility25. The trimer Me-(DPH)3 introduced here is distinguished by the inner unit being replaced by 1,6-dimethyl-diphenylhexatriene to study the impact of methyl substituents, as previously used in monomers and already established in carotenoids (for further synthetic details, see Supporting Information)1,27,28. Optical characterization confirms that Me-(DPH)3 retains comparable electronic properties to the previous system (DPH)3, supporting the use of these oligomers as comparable models to investigate high-spin state behaviour. Slight changes in net absorption of the S0–S2 electronic states are visible upon methylation, which is commonly seen in carotenoids where methyl-induced torsion slightly reduces effective conjugation and electronic delocalization29 (further discussed in Supplementary Note 4).

The trEPR spectra of (DPH)2, Me-(DPH)3, and (DPH)3 are shown averaged from 0 to 500 ns (blue). All spectra exhibit multiple transitions, indicating non-thermalized high-spin states. Common features in all spectra include absorptive/emissive transitions at 330 mT and 360 mT, respectively, with variations in outer transitions. Simulations (red, EasySpin30 parameters in Supplementary Table 1) and pulsed EPR measurements (Supplementary Fig. 1) identify the inner transitions as the ms = 0 → ±1 transition of the strongly correlated triplet pair 5TT, representing a pure quintet state with S = 25, 14. The zero-field splitting parameters |D|Q = 750 MHz and |E|Q = 80 MHz are consistent with the expected splitting of |D|T/3 (|D|T = 2450 MHz as shown later) for a coupled triplet pair 5TT in the strong exchange limit5,31. The lifetime of the quintet state (Fig. 1c) as well as the ability to measure 5TT in ODMR (see below) supports the appearance of a longer-lived pure quintet state within the strongly-coupled regime.

Several models have been proposed to describe how quintet state 5TT emerges from an initially formed S = 0 triplet pair 1TT. In the low-J regime, where the exchange interaction J(t) transiently becomes small and comparable to the zero-field splitting D, coherent singlet-quintet mixing can occur on nanosecond timescales5,16. A subsequent increase in J projects the mixed state onto 5TT, resulting in spin-polarized quintets. In contrast, another mechanism discussed in the literature includes J remaining large but dynamically fluctuating due to structural or vibronic motions, which can enable anisotropic spin-relaxation pathways into the quintet manifold32,33. These includes spin polarization transfer from 1TT or 5TT to weakly coupled T+T states, modulated by torsional conformations and dynamic J-coupling33. As we discuss below, our experimental data on the dimer suggests the latter picture—where J mostly remains high but fluctuates dynamically, briefly allowing spin-relaxation into 5TT without requiring persistent occupation of the weakly-coupled regime.

Whilst quintet state formation is verified in all three oligomers, triplet state formation differs, as represented in the additional outer transitions. A reduction of effective J can bring the system into a weakly-coupled triplet-pair manifold n(T…T) ↔ T1 + T1, in which the two triplets increase separation whilst preserving spin coherence. Thus, they inherit the selective ms = 0 level population, resulting in an eaaeea pattern (with microwave emission e and absorption a in the three canonical orientations, see explanation in Supplementary Note 6) with the D value of the triplet. Reviewing Me-(DPH)3, the outer transitions (shaded green) can be attributed to this pathway, evidenced by the selective ms = 0 population. The ZFS parameters |D|T = 2450 MHz and |E|T = 270 MHz match with those of the DEH-DPH monomer (Supplementary Fig. 2), suggesting the SF-derived triplet pairs extending to the outer chromophores.

In contrast, the triplet features in (DPH)2 and (DPH)3 cannot be solely reproduced by SF-derived triplet polarization. For the dimer (DPH)2, the observed triplet signal can be attributed to ISC origin, leading to a population of the zero-field sublevels of [px, py, pz] = [0 1.00 0.52] with |D|T = 2450 MHz. This assignment is supported by measurements on DEH-DPH monomers in dilute toluene solution, that can only undergo ISC and display the same pattern in trEPR (Supplementary Fig. 2). Thus, the dimer is effectively unable to access weakly coupled triplet states, as also indicated by the absence of a MFE (Supplementary Fig. 3), while still producing strongly coupled quintet states. This suggests that effective dissociation into weakly exchange-coupled triplet pairs is suppressed with two directly linked DPH chromophores. Instead, 5TT formation is enabled by subtle structural fluctuations that transiently modulate the exchange interaction J within a strongly coupled triplet pair, allowing spin evolution from 1TT to 5TT. This mechanism is consistent with theoretical predictions and was recently shown in acene dimers and macrocyclic pentacene dimers34–36. The observation of quintet states confirms that even the dimer undergoes fast initial singlet fission to 1TT, as also verified by TA measurements (see below). However, by establishing an equilibrium between nTT and emitting singlet states, an ISC pathway to T1 ultimately occurs. Notably, this ISC feature does not appear in trEPR of Me-(DPH)3 at 80K, excluding this ISC signal from being a relevant pathway in the formation of triplet pair states.

Strikingly, (DPH)3 exhibits a distinct spectral shape that does not correspond to SF or ISC mechanisms alone. However, by combining the simulation from Me-(DPH)3 with the ISC pattern from (DPH)2, the spectra can be accurately reproduced. While the SF-derived weakly-coupled triplet pairs in (Me)-(DPH)3, and the ISC-generated triplets in (DPH)3 and in the monomer exhibit a |D|T value of 2450 MHz, the ISC-generated triplet in (DPH)3 shows an increased |D|T, ISC value of 3500 MHz with [px, py, pz] = [0 1.00 0.52], indicating an increased localization within the trimer given the more complex energetic landscape37.

To selectively probe the quintet state, we measured the transitions at half the resonant magnetic field B0, known as the half-field (HF) signal (Fig. 1b)38. Me-(DPH)3 exhibits a derivative-shaped HF signal with both absorption and emission features, which can only stem from a quintet state with multiple possible transitions (see inset). Examining (DPH)3, we observe the same HF signal as the quintet state, along with an additional triplet HF signal. In contrast to SF-generated triplet states with selective ms = 0 population, ISC-derived triplets in (DPH)3 have sufficient spin polarization between ms = ±1 to generate a HF signal, confirming the observation from the trEPR spectra in full-field.

To better understand temporal spin state formation, we examined the time evolution of the EPR signal. Figure 1c displays the trEPR spectra for Me-(DPH)3 in 200 ns intervals up to 4 µs. Initially, the quintet signal (red shaded) dominates, peaking within the instrument response time (100 ns, grey shaded) and decays within a time of 2 µs. In contrast, the triplet signal (green) peaks later at 800 ns and displays a more prolonged decay. These timescales show that both states are long-living with the faster decay of the quintet state attributable to a pathway leading to measurable PL and providing optical readout, which will be discussed below.

Revealing quintet-mediated emission by spin-sensitive PL
Whilst EPR shows the possibility of manipulation of the high-spin states, readout can be performed by optical techniques, such as ODMR9,39. ODMR employs the principles of EPR by using microwave irradiation to alter the spin polarization between sublevels. Under continuous illumination, simulating realistic conditions, the PL readout changes as the sublevel population varies under magnetic resonance40.

Figure 2a presents the ODMR spectra (blue) including simulations (red) for the dimer (DPH)2 and both trimers, Me-(DPH)3 and (DPH)3, at T = 80K (see Supplementary Table 3 for simulation parameters), whilst the temperature dependence from 10K to 293K is discussed further below. The dimer displays only the response of the quintet state, whilst the ISC triplet does not participate in the PL, proving an optical pathway from the quintet state via the reverse SF pathway to the emissive singlet state (discussed below). The quintet state is also visible in both trimers, Me-(DPH)3 and (DPH)3, with the triplet pairs being visible as well at T = 80K. The spectral features are consistent with the EPR simulation in Fig. 1, confirming the assignment of quintet and triplet states. The pronounced HF signal (Supplementary Fig. 4) additionally confirms the involvement of the quintet state.

The possible involvement of the 3TT ↔ 3(T…T) states remains an open question for different singlet fission systems. Our magnetic resonance results suggest that their population and role may strongly depend on the extent of exchange coupling. In the dimer, only quintet states are observed in trEPR, with no corresponding triplet ODMR signal and no magnetic field effect. This is consistent with the absence of an (T…T) ↔ T1 + T1 population in this system, likely due to the short linker and rigid geometry preventing significant spatial separation between chromophores. Thus, the dimer appears to reside predominantly in the strongly exchange-coupled regime, where the only triplet signal detected by trEPR arises from ISC and does not contribute to luminescence. Therefore, the 5TT state is the only high-spin state participating in luminescence for the dimer.

In contrast, triplet features do appear in ODMR in the trimers, and their spectral shape provides insight into their origin. In particular, the Me-(DPH)3 triplet spectrum reveals only a characteristic ms = 0 overpopulation pattern in trEPR, which is a known signature of spin-polarized triplets formed from weakly-coupled n(T…T) ↔ T1 + T1 states (see Fig. 1a). Given the close proximity of the chromophores, such triplets could eventually recombine via short-range encounters, establishing a dynamic equilibrium that yields emissive and non-emissive triplet configurations. Especially at 80K, weakly-coupled triplet pairs persist long enough and remain sufficiently spin-polarized before subsequent triplet-triplet annihilation (TTA) that feeds population back into 1TT and, via thermal activation, into the emissive singlet state. These triplet encounters can appear in ODMR, even without full spatial separation, particularly shown for geminate n(T…T) ↔ T1 + T1 TTA at low temperatures41–43. We note that 3TT states may also transiently arise in this context, as they are a product of geminate TTA and intermediate spin-relaxation processes during triplet-triplet encounters. The dimer, which does not access a persistent weakly coupled regime, shows no triplet ODMR features even at low temperatures, further supporting the assignment to geminate TTA from n(T…T) ↔ T1 + T1 states.

Interestingly, ODMR at room temperature shows persisting quintet signal but vanishing triplet contribution (see detailed discussion below), indicating that the lifetime of the weakly-coupled triplet pairs until following encounter becomes too short to retain detectable spin polarization under ambient conditions. This is consistent with previous ODMR studies, where TTA-derived triplet resonances are detected only at cryogenic temperatures, due to the much shorter encounter lifetimes at higher temperatures40,42,43. In contrast, 5TT remain sufficiently long-lived at all temperatures and is therefore the only high-spin species detected by ODMR at room temperature (further explanation about ODMR signals in Supplementary Note 7).

These insights are further supported by temperature-dependent transient photoluminescence (trPL) data. The temperature-dependent trPL data of Me-(DPH)3 (Fig. 2b) show a persistence of delayed PL for up to hundreds of microseconds, confirming the participation of high-spin states. The temperature dependence of the PL shows, whilst maintaining the same PL spectrum with time (Supplementary Fig. 5), a multicomponent decay with reduced dynamics upon temperature decrease. The behaviour is reminiscent of previous observations in MOF systems with a similar temperature dependence of multicomponent decay in ns TA, where reduced conformational motion at low temperatures was found to slow down spin state interconversion and decay8. This is consistent with the ODMR observations, where low temperatures stabilize weakly-coupled triplet pairs, while at room temperature triplet-triplet encounters occur on shorter timescales, limiting their detectable steady-state lifetime. The PL spectral shape changes slightly with temperature in Me-(DPH)3 (Supplementary Fig. 6), with a small reduction in vibronic structure and S0–S2 intensity at higher temperatures, suggesting increased conformational disorder that can subtly influence triplet-pair coupling as seen in carotenoids44.

Integrated PL (Fig. 2c) shows that 99.99% of the emission occurs within 2 µs at all temperatures. In line with the previous discussion, higher temperatures reach this threshold faster. EPR data presented earlier revealed quintet states decaying within 2 µs, consistent with negligible PL after the same time, suggesting that quintet states predominantly contribute to the delayed PL at room temperature, confirmed by ODMR results at 295K (see below). Notably, all three oligomers, including (DPH)2 without persistent population of weakly-coupled triplet pairs, show a comparable trPL decay at room temperature (Supplementary Fig. 7). Whilst they all show equivalent generation and emission of quintet states, the similarity of trPL in all oligomers at ambient conditions hints that emissive products of triplet encounters contribute only a minor fraction to the luminescence at ambient conditions.

The nature of the intermediate triplet pair states in Me-(DPH)3 can be further probed via PL under applied magnetic field (Fig. 2d). The MFE and the underlying mechanisms in DPH crystals and films have been extensively explored in previous studies45–47. The zero-crossing at 50 mT in Me-(DPH)3 is comparable to the zero-crossing typically seen in intermolecular DEH-DPH systems (Supplementary Fig. 8), with both exhibiting the same zero-field splitting value D24. However, whilst the overall MFE shape in Me-(DPH)3 is similar to the previously reported MFE in DPH, variations lie in the time dependence. The initial 15 ns show no magnetic field dependence, followed by emerging effects at 30–40 ns. This agrees with a magnetic-field-independent decay of ns TA (Fig. 4b, see below), indicative of initially strongly-coupled triplet pairs formed and contributing to PL. After 40 ns, the system exhibits a MFE contrast, increasing to up to 140% for 100–300 ns after photoexcitation, proving that the weakly-coupled triplet pair regime is entered. This aligns with the EPR measurement of the trimer, which reveal an overpopulation of the ms = 0 triplet sublevels, characteristic of spin-polarized triplet originating from weakly-coupled n(T…T) ↔ T1 + T1 states. The MFE effect results from suppressed spin-mixing by introducing Zeeman splitting, reducing the formation of T1 states and leading to an increase in radiative decay via singlet states (further discussion MFE effect can be found in Supplementary Note 8)48. Notably, the MFE response diminishes significantly at 1–2 µs, at later times becoming nearly undetectable (Supplementary Fig. 9). This overlaps with the lifetime of 5TT states that feeds back into the emissive singlet state, and suggests a dynamic equilibrium between 5TT, 1TT and n(T…T) states with ongoing spin evolution into the triplet-pair manifold during this period. The persistence of a MFE effect up to room temperature but with faster decay kinetics (Supplementary Fig. 9) indicates that the weakly-coupled regime is accessed even under ambient conditions but depopulates more rapidly.

In the low-field regime (below 50 mT), this character can be distributed to a maximum of six states (when D1 and D2 are identical), which explains the observed decrease in PL. At higher fields (above 50 mT), the singlet character becomes restricted to just two states, resulting in a positive MFE. As Thompson et al. have pointed out, if the singlet character were distributed across all nine states at zero field, a monotonic MFE would be observed without a distinct low-field effect (<50 mT). However, this is not the case for the DPH system studied here, as evidenced by Figure 2d.

(PRL, 2014) and Joshi et al. (JCP, 2022). These seminal works established the observation of triplet-derived ODMR signatures at cryogenic temperatures. In our revised manuscript we explicitly cite and discuss these reports in the context of the low-temperature triplet ODMR features we also observe (see revised lines 218 - 250). However, in contrast to these earlier studies, our work demonstrates for the first time room-temperature ODMR dominated by quintet (5TT) states in a molecular singlet fission system. To our knowledge, this room temperature quintet ODMR has not been previously shown and is the central novelty of our contribution. We also note that Reviewers 2 and 4 explicitly recognized the novelty of detecting quintet emission at room temperature, which supports the significance of this result.\nIn the revised manuscript, we have more explicitly clarified the structure-property relationships and how the methylated trimer differs from our previously studied DPH systems (Millington et al., JACS 2024). On the one hand, our work extends the previous structure–property discussion by examining the formation and emission of high-spin states in the unmethylated and methylated DPH oligomers. On the other hand, the newly introduced methylated trimer provides a reduction of ISC pathways that remain active in (DPH) by introducing methyl groups. In optical data (S12), methylation of the central DPH unit in Me-(DPH) shows a slight vibronic reweighting of the S →S absorption, consistent with methyl-induced torsion that slightly reduces effective conjugation and electronic delocalization. These methyl groups facilitate access to weakly coupled triplet-pair states by subtly reducing planarity and introducing low-frequency torsional motions. Such motions can enhance 1TT – 5TT mixing relative to ISC, consistent with negligible ISC contributions above 80 K. This is further supported by the temperature dependent measurements, where ISC contributions in EPR only appear below 80K where methyl motions are frozen. We have now made this structural comparison and its impact on spin dynamics more explicit in the revised manuscript (lines 118-121, lines 316-320 and discussion point (iii)).\nRegarding the connection to our earlier JACS work on DPH oligomers, we have clarified how the present results extend that picture. Our previous optical-only assignment of the TA plateau was based on spectral similarity to sensitized triplets and consistent kinetics, leading us to assign it primarily to T +S products. Those criteria remain compatible with 1 0 a contribution from isolated triplets and we are able to extend the picture with high-spin states that are possible to probe with the magnetic resonance measurements. The spin-resolved data show that the additionally long-lived quintet 5TT populations persist into the plateau and feed other triplet-pair configurations, as weakly-coupled pairs, within their lifetime of few µs. In the revised manuscript, we explicitly discuss the previous and additional insights with focus on Me-(DPH) and that the beginning of the plateau 3 plausibly reflects a mixed multiexciton manifold comprising triplet pairs, followed by triplet encounters and their products, and isolated triplet excitons – consistent with both our optical and magnetic-resonance observations. At later times, where luminescence reaches unity and 5TT states are decayed, only isolated triplet states remaining, in agreement with out earlier report.\n2. Previously, I raised concerns regarding the use of the term \"ISC\" in this manuscript and the potential role of the 3(TT) state as an intermediate. While I understand the authors' intention to describe the 1(TT) → T₁ transition as an intersystem crossing (ISC) process, the rationale for completely excluding the 3(TT) state from their interpretation is unconvincing. According to the Wigner–Eckart theorem, the transition between 1(TT) and 3(TT) is forbidden; thus, 3(TT) can only be generated from 5(TT). In other words, 3(TT) cannot interact or mix with 1(TT) at all. As a result, 3(TT) should not be optically detectable as a differential PL signal in ODMR. The authors may argue that 3(T⋯T) could be formed from 1(T⋯T) in a weakly interacting regime, but based on the MFE trace shown in Figure 2d, I do not believe this scenario applies to the DPH systems studied here. Microwave pumping and subsequent ODMR detection of individual triplets represent a fundamentally different situation, which only applies when two triplets encounter each other in a nongeminate fashion. I also note that Reviewer 2 raised serious concerns regarding the omission of 3(TT) in the authors' interpretation. This issue must be addressed seriously with careful consideration.\nWe agree with the reviewer’s suggestions of triplet encounters as origin of the ODMR signal. As already suggested in the previous revised manuscript, we assigned the ODMR signal at low T as arising from triplet encounters. In the current manuscript, we extended our explanation of the triplet ODMR signal with reference to TTA and why it vanishes at room temperature, which is in accordance to literature:\nODMR detection can happen in nongeminate and geminate triplet encounters, as previously shown in low temperature ODMR in singlet fission by Bayliss et al (PRL, 2014), and Joshi et. al (JCP, 2022). At low temperature, weakly coupled (T…T) states can persist long enough to undergo spin-selective recombination via TTA, feeding population back into 1TT and, via thermal activation, to the emissive S* state. Microwave irradiation in resonant conditions induces transitions between the triplet sublevel populations, altering the fraction of encounters that yield 1TT, and thus producing the observed triplet ODMR features. This mechanism is a well established origin of triplet signal in both geminate and non-geminate TTA, as shows in singlet-fission systems at cryogenic temperatures (references above) or as we showed previously in OPV films (Grüne et al., Adv. Funct. Mater. 2022). We also note that the dimer, which does not access a persistent weakly coupled regime, shows no triplet ODMR features even at low temperatures, further supporting the assignment to geminate TTA from (T…T) states. We emphasize that this assignment does not require invoking a direct 1TT → 3TT pathway, which is spin-forbidden by the Wigner–Eckart theorem. Instead, triplet features arise naturally from spin-polarized triplets generated during (T…T) encounters, consistent with established low-temperature ODMR studies.\nHowever, at higher temperatures, the triplet-pair lifetime before TTA becomes too short to maintain detectable spin polarization within the ODMR detection bandwidth. This explains the absence of triplet resonances in the room-temperature spectra and why all TTA-originated ODMR spectra are measured at cryogenic temperatures. However, 5(TT) remains sufficiently long-lived at all temperatures and is therefore the only high-spin species detected by ODMR at room temperature. We also note that we showed earlier that high-spin states can be ODMR-visible at room temperature in related quartet (S = 3/2) systems when they do not recombine rapidly via annihilation pathways such as TTA (Gorgon et al, Nature 2023). To our knowledge, our present study is the first to demonstrate optical detection of quintet (S = 2) states in singlet fission by ODMR at room temperature, which constitutes a key novelty of this work.\nWhilst we thus don’t exclude 3TT forming as a transient species in this process, we clarify the mixing mechanisms between 1TT and 5TT and the absence of 1TT – 3TT mixing in our response to the next question.\n3. In my comments 3 and 4, I raised questions regarding the origin of the MFE in the DPH systems studied here. However, the authors’ explanation of the low-field effect (below 50 mT) is not convincing. The authors responded that “the spin character is distributed across all nine TT states at zero field” and that “subtle field-induced rephrasing and spin-spin interactions can suppress the formation or recombination of emissive singlet states, leading to a negative fluorescence MFE at low fields.” This explanation does not align with the previous study by Thompson et al., which the authors referenced in their response, nor with other well-established works by Merrifield et al. (Pure and Applied Chemistry, 1971) and Steiner et al. (Chemical Reviews, 1989). At zero field, the singlet character should be confined to only three states. In the low-field regime (below 50 mT), this character can be distributed to a maximum of six states (when D1 and D2 are identical), which explains the observed decrease in PL. At higher fields (above 50 mT), the singlet character becomes restricted to just two states, resulting in a positive MFE. As Thompson et al. have pointed out, if the singlet character were distributed across all nine states at zero field, a monotonic MFE would be observed without a distinct low-field effect (<50 mT). However, this is not the case for the DPH system studied here, as evidenced by Figure 2d. Instead, the observation in Figure 2d suggests an evolution in the distribution of the singlet character, transitioning from three to six states, and then from six to two states, as the magnetic field strength increases. This scenario excludes any mixing or interaction between 1(T⋯T) and 3(T⋯T), indicating that the interaction occurs solely between symmetric states, 1(TT) and 5(TT).\nWe thank the reviewer for pointing out this important clarification. We agree that our earlier wording was imprecise in describing the field-dependent redistribution of singlet character in the triplet–triplet manifold. Following the framework of Steiner (Chem. Rev. 1989), and the analysis by Thompson et al. (Phil. Trans. R. Soc. A, 2015), the singlet character is not distributed over all nine TT states at zero field. Instead, at zero field it is confined to three states, expands to a maximum of six states in the low-field regime (<50 mT, for identical triplets), and is then restricted to two states at higher fields as the Zeeman interaction dominates. This redistribution explains the negative-to-positive magnetic field effect observed in our DPH oligomers, and is fully consistent with the lineshape in Figure 2d. The reviewer pointed out correctly, if singlet character were indeed distributed over all nine states at zero field, only a monotonic MFE would be expected, as is seen for solution-phase tetracene in the given reference. We have corrected our explanation accordingly in the revised Supporting Information.\nOur ODMR and trEPR experiments are carried out in the high-field regime (X-band, ~340 mT), which is why we more focused more on the spin states in this regime. The EPR data further support a predominant mixing within the 1TT–5TT manifold, as suggested by the magnetic field measurements, for the following reasons: The dimer does not access a weakly coupled regime, as evidenced by trEPR and the absence of magnetic-field-dependent PL, but generates quintet states. 5TT formation is enabled by subtle structural fluctuations that transiently modulate the exchange interaction J within a strongly coupled triplet pair, allowing spin evolution from 1TT to 5TT, as recently shown in macrocyclic pentacene dimers by Ishi et al (J. Am. Chem. Soc. 2024). According to the Wigner–Eckart theorem, direct 1TT → 3TT transitions are symmetry-forbidden and would only appear through symmetry breaking. It would manifest as ISC-like polarization pattern, similar to 5TT → 3TT conversion. However, such symmetry breaking should be equally or even more pronounced in Me-(DPH)₃, yet no ISC-like signal is observed in this system. This strongly suggests that the ISC signatures detected in the dimer originate from direct ISC into T , rather than from 1TT–3TT or 5TT–3TT conversion, also in agreement with Ishi et al, 2024.\nThis assignment is reinforced by the polarization patterns: the ISC signal in the dimer is identical to that of the DPH monomer, whereas 1TT–3TT (or 5TT–3TT) mixing would lead to different zero-field population patterns. In Me-(DPH) , the presence of methyl groups introduces torsional motions that enhance electronic–vibrational coupling, thereby facilitating efficient 1TT–5TT mixing while suppressing ISC-like signatures. The additional ISC features visible in (DPH) and (DPH) at temperatures below 80 K, when molecular motions are frozen out, are also consistent with this picture."}, {"round": 2, "reviewer_comments": {"reviewer_1": "The revised version of the manuscript shows substantial improvement in both clarity and scientific depth compared with the earlier submission. The authors have clearly refined the description of their experimental results and significantly strengthened the mechanistic interpretation of high-spin state dynamics in diphenylhexatriene-based oligomers. The study convincingly demonstrates the formation and emission of quintet states in intramolecular singlet fission systems and provides valuable insight into how triplet and quintet pathways can be tuned through molecular architecture. The discovery that quintet-state emission dominates delayed fluorescence up to room temperature is particularly intriguing, as it highlights an unusual and rarely explored spin-mediated radiative process in organic systems. This observation not only extends the conventional understanding of singlet fission photophysics but also suggests new opportunities for exploiting high-spin states in quantum photonics and optoelectronic applications. The manuscript’s focus on distinguishing between intersystem crossing and genuine singlet-fission-derived triplet-pair formation is both timely and important. The identification of the Me-(DPH)₃ trimer as the only system that cleanly follows the desired singlet fission pathway is well supported by the data and represents a meaningful contribution to the field. The authors’ use of complementary spin-sensitive optical techniques is a particular strength, though the specific methods employed could be described more explicitly to aid the broader readership of Nature Communications. While the abstract and manuscript are much improved, a few points would benefit from additional clarification to further strengthen the work before publication. In particular, the statement that quintet-state optical emission dominates delayed fluorescence would be more convincing if accompanied by quantitative details or clear mention of the observables used to identify and compare the relevant spin states—such as time-resolved intensity ratios, kinetic rate constants, or magnetic-field-dependent emission data. Moreover, although the distinction between weakly exchange-coupled triplet pairs and quintet emission channels is conceptually interesting, the physical origin of the quintet emission remains somewhat ambiguous. It would be valuable to indicate whether this emission results from radiative recombination of correlated triplet pairs or from a separate spin-allowed relaxation channel. A concise schematic energy diagram or kinetic model in the Supplementary Information could clarify this point and provide greater mechanistic transparency. The manuscript would also benefit from a more explicit comparison to well-established singlet fission systems such as tetracene or perylene bisimide dimers, which would help position the novelty of DPH-based oligomers in the broader SF landscape. From a presentation perspective, the text is generally clear and well written, but the abstract could place slightly stronger emphasis on the conceptual significance of identifying emissive quintet states, rather than on the enumeration of molecular structures. Overall, the present version represents a notable improvement and now meets the standards of scientific quality, novelty, and presentation expected for publication in Nature Communications. The work is technically sound, the conclusions are well supported by the data, and the topic will likely attract broad interest from the communities studying high-spin photophysics, singlet fission, and organic optoelectronics. With minor clarifications—mainly to improve mechanistic clarity and contextual framing—the manuscript will make a strong and timely contribution. I therefore recommend acceptance after minor revision.", "reviewer_2": "This reviewer is fully satisfied with the revisions. Thus, the present version is worthy of publication.", "reviewer_4": "please see the attached file"}, "author_response": "We thank the reviewer for the positive and encouraging assessment of our revised manuscript. We greatly appreciate the recognition of the improved clarity and mechanistic interpretation, as well as the significance of identifying emissive quintet states in intramolecular singlet fission systems.\nWe are happy to strengthen the description and complementarity of the diPerent techniques used. In particular, the combination of the techniques of TA, trEPR, trPL (with magnetic field) and ODMR is a strength to track the triplet and quintet formation, evolution and emission across timescales, as we describe in the following and added to the Supporting Information, section 3.\nComplementarity of TA, trEPR, trPL and ODMR techniques\nTo measure the full sequence of spin-state formation and emission in singlet fission, we require multiple complementary techniques (Table R1). Transient absorption (TA) provides the fastest temporal resolution, directly revealing how and when triplet pairs formed which is important to prove fast triplet pair formation. However, the lack of spin selectivity requires paramagnetic techniques such as electron paramagnetic resonance (EPR). Transient EPR (trEPR) adds spin selectivity, identifying whether triplet and quintet states are occupied. An important advantage of trEPR is the ability to track the populations mechanism of these states via singlet fission or ISC, however, the technique is usually limited to cryogenic temperatures.\nOptical detection methods bridge these regimes: transient PL traces delayed fluorescence in high sensitivity up to several hundreds of microseconds. It provides the temporal decay of emissive states as well as the corresponding spectra. However, to identify which paramagnetic species are in the delayed fluorescence, optically-detected magnetic resonance (ODMR) with its spin-selectivity is required. ODMR uniquely identifies paramagnetic species (quintet or triplet) that contribute to luminescence and can be even measured up to room temperature given its good sensitivity.\nBy combining these complementary approaches, we connect ultrafast population dynamics (TA) with spin-resolved formation pathways (trEPR) and emissive high-spin channels (ODMR), allowing a complete description of the formation and emission of high-spin states in these singlet fission systems. The following table provides and overview about the key information provided by the individual techniques as well as the advantages and limitations.\nTable R1.

The magnetic field response appears within ~40 ns after excitation, indicating that the singlet population has already decayed and the delayed PL originates from high-spin states. Integration of the PL signal beyond 40 ns shows that this delayed component accounts for approximately 10% of the total emission until 2µs. This timescale is in agreement with the decay of the 5TT population observed in trEPR and leads to the quintet ODMR at room temperature. The trPL is comparable for all three compounds at room temperature, including the dimer that does not enter the weakly-coupled regime and only has emission via quintet states. Thus, these quantitative comparisons substantiate our conclusion that quintet-state emission dominates the delayed fluorescence channel in about 10% of the total emission. We added these quantitative arguments with relevant kinetic rates to the Supporting Information, section 10, and referred to it in the main discussion.\nMoreover, although the distinction between weakly exchange-coupled triplet pairs and quintet emission channels is conceptually interesting, the physical origin of the quintet emission remains somewhat ambiguous. It would be valuable to indicate whether this emission results from radiative recombination of correlated triplet pairs or from a separate spin-allowed relaxation channel. A concise schematic energy diagram or kinetic model in the Supplementary Information could clarify this point and provide greater mechanistic transparency.\nWe thank the reviewer for raising this important point. We now clarify in the revised manuscript that the observed emission originates from spin-allowed recombination of the 5TT manifold back to the singlet state, rather than from direct radiative decay of 5TT itself. This pathway is the spin-reverse counterpart of the forward singlet-fission process (S ® 1TT ® 5TT), enabled by exchange-coupling fluctuations J(t) that mix singlet and 1 quintet character and enabling the same pathway in the back direction (5TT ® 1TT ® S ). 1 Such ODMR signals from “back pathways” via the emissive singlet state are well established in related systems: for instance, triplet-mediated delayed fluorescence in donor-acceptor OLEDs via a similar T ® S conversion (Bunzmann et al., Mater. Horiz. 1 1 2020), and quartet-mediated emission Q ® S has been reported in radical-anthracene- 1 1 linked systems (Gorgon et al., Nature 2023).\nImportantly, we do not observe any measurable spectral shift in the delayed photoluminescence relative to prompt emission, consistent with recombination via the singlet state rather than from a distinct direct, also spin-forbidden, emissive 5TT level. We therefore describe this process as “quintet-mediated emission”, since the quintet state acts as a long-lived reservoir that feeds the emissive singlet channel. This interpretation reconciles the time-resolved PL, trEPR, and ODMR data and we have clarified this also in the main text, line 344-347, and 449-451. In addition, we included a new complete schematic diagram including this pathway and other obtained important kinetics in the Supporting Information Fig. S17 and Section 10.\nThe manuscript would also benefit from a more explicit comparison to well-established singlet fission systems such as tetracene or perylene bisimide dimers, which would help position the novelty of DPH-based oligomers in the broader SF landscape.\nWork on tetracene oligomers (Wang et al., Nat. Chem. 2021) has shown that increasing the number of chromophore units enables access to spatially separated, weakly coupled triplet pairs 1(T…T), which enhances free-triplet generation compared with dimers that primarily populate adjacent 1TT states. This established a structural modulation, based on chromophore number and geometry, for the degree of inter-triplet coupling and triplet separation. Our DPH oligomers are consistent with this picture where trimers can access a weakly coupled (T…T) manifold at low temperature, as seen in ODMR and trEPR, whereas the dimer does not enter it persistently. However, our study goes beyond triplet-yield optimization by directly resolving and exploiting the quintet 5TT manifold: we observe 5TT formation in all oligomers and quintet-mediated delayed fluorescence up to room temperature, detected by ODMR.\nSimilar studies on perylene dimers (Hong et al, Nat. Comm. 2022) highlight that low-frequency conformational motions and interchromophore coupling influences access to distinct multiexciton manifolds. Consistent with that principle, our DPH oligomers show that methylation modulates low-frequency torsions, biasing triplet-pair mixing relative to ISC. However, our scope and outcome diPer: prior perylene/tetracene studies optimized free-triplet yields but did not directly address quintet formation or emission. Here, we identify the 5TT manifold spectroscopically and show that it feeds delayed fluorescence via spin-allowed back-transfer the emissive singlet state. To our knowledge, room-temperature optical detection of emissive quintets acting as an emissive reservoir has not been reported for tetracene or perylene oligomers.\nBut also in terms of triplet formation for singlet fission applications, DPH oPers an important advantage: the DPH oligomers have a triplet energy of ~1.5 eV, well above the silicon bandgap and higher than that of tetracene (~1.25 eV) or perylene (~1.1 eV), making it a promising singlet-fission material for silicon solar cells. Thus, DPH oligomers bridge the gap between energy-conversion systems and quantum-applications, establishing a new regime where high-spin states are not only intermediates but functional emissive states that can be used towards molecular quantum-optical applications. To position our DPH oligomers in the broader landscape, we added this comparison to the Supporting Information, Section 11.\nFrom a presentation perspective, the text is generally clear and well written, but the abstract could place slightly stronger emphasis on the conceptual significance of identifying emissive quintet states, rather than on the enumeration of molecular structures.\nWe thank the reviewer for this helpful suggestion. We have revised the abstract to place stronger emphasis on the significance of quintet-mediated emission, highlighting their role as a new functional channel in singlet fission and their relevance for high-spin photophysics. The revised abstract now emphasises more the emissive quintet states up to room temperature and discuss the broader implications for spin-photon interfaces and molecular quantum applications.\nOverall, the present version represents a notable improvement and now meets the standards of scientific quality, novelty, and presentation expected for publication in Nature Communications. The work is technically sound, the conclusions are well supported by the data, and the topic will likely attract broad interest from the communities studying high-spin photophysics, singlet fission, and organic optoelectronics. With minor clarifications—mainly to improve mechanistic clarity and contextual framing—the manuscript will make a strong and timely contribution. I therefore recommend acceptance after minor revision.\nWe thank the reviewer for this very positive evaluation and for recommending acceptance after minor revision. We have carefully implemented all requested clarifications to further strengthen the mechanistic discussion and clarity of the manuscript."}, {"round": 3, "reviewer_comments": {"reviewer_1": "The revised manuscript presents a comprehensive and elegant study on high-spin state formation and emission processes in intramolecular singlet fission (iSF) systems based on diphenylhexatriene (DPH) dimers and trimers. The authors employ a set of spin-sensitive spectroscopic techniques to convincingly demonstrate the formation of pure quintet states and their role in quintet-mediated delayed fluorescence up to room temperature. The detailed distinction between triplet-pair formation, intersystem crossing (ISC) pathways, and the selective SF dynamics in Me-(DPH)₃ provides valuable insight into spin-state control and emissive behavior in molecular systems.\nAfter two rounds of revision, I find that the authors have thoroughly addressed the previous reviewer comments and significantly improved both the clarity and scientific rigor of the manuscript. The presentation is now clear and coherent, the experimental evidence is convincing, and the discussion appropriately situates the findings within the context of high-spin photophysics and molecular quantum applications.\nIn my view, the manuscript has now reached a high standard suitable for publication. It makes an important contribution to the understanding of spin dynamics and emissive quintet states in iSF materials, and I therefore recommend it for publication in its present form.", "reviewer_4": "I am satisfied with the changes made by the authors in response to my questions, as well as to the questions from the other reviewer.
