AbstractLuminescent materials require systems that exhibit both dual‐state emission (DSE) and aggregation‐induced emission (AIE) to overcome the limitation of aggregation‐caused quenching (ACQ). Herein, a molecular assembler capable of crafting nanowires that exhibit programmable fluorescence across a broad spectrum of colors in a precisely quantized manner is reported. Because it is a starburst dendritic box made of PAMAM dendrimer (P), controller (C) molecules, and motor (M) molecules, the assembler is called PCM. Here, Nile red is chosen as C and placed into the hollow core of the dendrimer; a double ratchet motor (DRM) is chosen as M and is connected to the N‐terminals of the PAMAM dendrimer. While aqueous dispersed PCM assemblers have broad fluorescence bands beyond 300 nm, their crafted nanowires produce quantized cyan‐green, yellow, and orange‐red light emission in the spectra. These PCM assemblers are shown to hold long‐term memory, rapid switching, and energy harvesting by modulating photonic bandgaps, causing a longer redshift in the solid phase. The DSE of PCM can yield versatile photonics applications like bioimaging and energy harvesting. As PCM nanowires can modulate photonic bandgaps to cause a longer redshift, PCM fluorophores hold promise for drug delivery and cell separation like infrared‐sensitive operations.

Published: July 2024

AbstractStructurally flexible organic porous molecular arrays are promising for the development of vapochromic materials with superior detection performance. Exploring the photophysical control of vapochromic materials using these molecular arrays is important for the design of new vapochromic materials. However, difficulties arise in the formation and control of organic porous molecular arrays owing to weak and less‐oriented noncovalent forces and their tendency to arrange into energetically preferred high‐density configurations. Herein, an efficient strategy is presented to control molecular arrays by manipulating the shapes of donor–acceptor–donor system‐based molecular building blocks using positional isomerism and report on the correlation between controlled molecular arrays and vapochromic behavior. Depending on their shape (Z‐shaped, quasi‐Z‐shaped, or linear shape), the building blocks formed different molecular arrays that controlled the intermolecular interactions and void volumes. This led to differences in the final microstructural morphologies. Consequently, they exhibited different vapochromic behaviors, and an in‐depth understanding of the correlation between the molecular arrays and vapochromism/vapofluorochromism is obtained.

AbstractVan der Waals heterostructures (vdWHs) consisting of 2D materials offer a practical and effective approach for engineering multifunctional, high‐performance photodetectors. However, 2D vdWHs photodetectors based on photoconductive effects require an external power input and are often accompanied by a large dark current, which hinders the development of miniaturization and portability of devices and greatly limits the application of devices in complex environments. Herein, a self‐powered photodetector constructed from an InSe/PtS2 vdWH with an extremely low dark current (≈10−14 A) at zero bias and a large rectification ratio of 5.1 × 103 is reported. Leveraging the robust built‐in electric field of the InSe/PtS2 vdWH, the device demonstrates pronounced photovoltaic effects, characterized by an open‐circuit voltage of 0.395 V and a substantial short‐circuit current of 37.1 nA. Remarkably, a high responsivity and detectivity of 211 mA W−1 and 8.58 × 1012 Jones, an excellent light on/off ratio of 0.8 × 107 , and a fast response time of 465/470 µs are achieved, at zero bias. The device showcases a broadband self‐powered photoresponse spanning from 265 to 1064 nm. This study demonstrates the high potential of the InSe/PtS2 vdWH for broadband self‐powered photodetector applications.

Inspired by natural photonic crystals such as butterfly scales, a series of artificial photonic crystals are developed for use in integrated photonic platforms, biosensing, communication, and other fields. Among them, colloidal photonic crystals (CPCs) have gained widespread attention due to their excellent optical properties and advantages, such as ease of preparation and functionalization. This work reviews the classification and self‐assembly principles of CPCs, details some of the latest biomedical applications of large‐area, high‐quality CPCs prepared using advanced self‐assembly methods, summarizes the existing challenges in CPC construction and application, and anticipates future development directions and optimization strategy. With further advancements, CPCs are expected to play a more critical role in biosensors, drug delivery, cell research, and other fields, bringing significant benefits to biomedical research and clinical practice.

AbstractThe advancement of conventional lithium–sulfur batteries (LSBs) is hindered by the shuttle effect and corresponding safety issues. All‐solid‐state lithium–sulfur batteries (ASSLSBs) substitute the liquid electrolytes with solid‐state electrolytes (SEs) to completely isolate the cathode and anode, thereby effectively suppressing polysulfide migration and growth while significantly enhancing energy density and safety. However, the development of ASSLSBs is accompanied by several challenges such as the formation of Li dendrites, electrode degradation, poor interfacial wettability, and sluggish reaction kinetics, etc. This review systematically summarizes the recent advancements made in ASSLSBs. First, a comprehensive overview of the research conducted on advanced cathodes utilizing sulfur (S) and lithium sulfide (Li2S) is displayed. Subsequently, the SEs are classified and discussed that have been implemented in ASSLSBs. Furthermore, the issues of interfaces and anodes in ASSLSBs are analyzed. Finally, based on current laboratory advancements, rational design guidelines are proposed for each component of ASSLSBs while also presenting four practical recommendations for facilitating early commercialization.

AbstractThe power conversion efficiency (PCE) of perovskite solar cells (PSCs) is approaching their Shockley‐Queisser (S‐Q) limit through numerous efforts in key parameters improvement. To further approaching the limit, it is important to facilitate the fill factor (FF), a parameter closely related to carrier transport and nonradiative recombination. Herein, an interfacial bridging strategy is proposed to improve FF, which utilizes functional graphene quantum dots at the tin oxide (SnO2)/perovskite buried interface. As a result, synergistic effects of enhanced conductivity of SnO2, preferable energy alignment at the buried interface and improved perovskite crystal orientation are realized. The champion FF reaches 85.24% in formamidinium lead iodide (FAPbI3) based PSCs, which ranks among the highest in the n‐i‐p structure. Such strategy is also proven successful in other perovskite systems, where the champion PCE reaches 24.86% in the formamidinium‐cesium (FACs)‐based devices and 24.44% in the flexible devices. Therefore, this work provides a practical design rule for pursuing high FF of PSCs with carbon materials.

Authors: Wang Liping , Riedel Sibylle , Zhao‐Karger Zhirong 
Published: July 2024

AbstractDivalent metal batteries have attracted considerable attention in scientific exploration for sustainable energy storage solutions owing to the abundant reserves of magnesium (Mg) and calcium (Ca), the competitive low redox potentials of the Mg/Mg2+ (–2.37 V vs SHE) and Ca/Ca2+ (–2.87 V vs SHE) couples, as well as the high theoretical capacities of both metal anodes. However, the development of these batteries faces fundamental challenges stemming from the limited cycling stability and efficiency of Mg/Ca metal anodes. These issues primarily originate from the sluggish electrochemical redox kinetics of the divalent metals, particularly at the anode‐electrolyte interfaces. This comprehensive review provides an up‐to‐date overview of advancements in the field of the anode‐electrolyte interface for divalent metal batteries, covering aspects ranging from its formation, morphology, and composition to their influence on the reversible electrochemical deposition of divalent metals. Recent approaches aimed at enhancing the performance of metallic Mg and Ca anodes across various electrolytes are summarized and discussed, with the goal of providing insights for the development of new strategies in future research.

Exploring Two‐Exciton Steerability and Nonlocality Dynamics in Two Open Microcavities Coupled by an Optical Fiber
Authors: Aldosari F. M. , Hashem M. 
Published: July 2024

AbstractThis work will explore the generations of quantum nonlocalities (as entanglement, Bellnonlocality, and steerability) for two quantum wells (excitons) in dissipative microcavities containing a linear optical medium. An optical fiber links the microcavities. The generated two‐exciton nonlocalities are explored by using Bell inequality, steering inequality, and entanglement of formation. For initial correlated and uncorrelated states, the ability of the excitation–photon–fiber interactions to produce new generation and robustness of the two‐exciton nonlocality is investigated under the effects of the couplings of the exciton–photon and fiber–photon interactions as well as of the dissipations and the optical susceptibility. It is found that increasing the optical susceptibility enhances the regularity and amplitudes, reduces the frequencies of two‐exciton nonlocality dynamics, and supports dissipation degradations. For the initial uncorrelated state, decreasing the difference between the exciton–photon and fiber–photon couplings enhances the generations of the nonlocalities. For the initial correlated state, increasing the exciton–photon and fiber–photon couplings enhances the nonlocality conservation. For open microcavites, increasing the exciton–photon and fiber–photon couplings and the difference between them supports the nonlocality degradations resulting from the external environment dissipations.

AbstractMetasurfaces, composed of arranged nanoscale particles, manipulate electromagnetic waves for tailored physical properties. Recently vortex beams, carrying orbital angular momentum, have been generated through metasurfaces to realize diverse applications. Here, the study introduces a metasurface capable of generating dual‐mode vortex beams, which combines the functionalities of chiral metalenses and vortex beam generation. These dual‐mode vortex beams exhibit varying characteristics depending on the polarization state of the incident light, offering improved control over orbital angular momentum. This advancement holds promise for enhancing applications such as optical communication, optical tweezers, and imaging for overcoming diffraction limit. By employing titanium dioxide (TiO2) for its efficiency, the design concept is validated through simulations and discuss considerations for fabrication. The proposed approach paves the way for compact optical systems with heightened adaptability.

AbstractSystematically orchestrating fundamental building blocks into intricate high‐dimensional molecular assemblies at molecular level is imperative for multifunctionality integration. However, this remains a formidable task in crystal engineering due to the dynamic nature of inorganic building blocks. Herein, we develop a multi‐template‐guided strategy to control building blocks. The coordination modes of ligands and the spatial hindrance of anionic templates are pivotal in dictating the overall structures. Flexible multi‐dentate linkers selectively promote the formation of oligomeric assembly ([TeO3(Mo2O2S2)3O2(OH)(C5O2H7)3]4− {TeMo6}) into tetrahedral cages ([(TeO3)4(Mo2O2S2)12(OH)12(C9H9O4P)6]8− {Te4Mo24} and [(AsO4)4(Mo2O2S2)12(OH)12(C9H9O6)4]12− {As4Mo24}), while steric hindrance from anionic templates further assists in assembling cages into an open quadruply twisted Möbius nanobelt ([(C6H5O3P)8(Mo2O2S2)24(OH)24(C8H10O4)12]16− {P8Mo48}). Among these structures, the hydrophilic‐hydrophobic hybrid cage {Te4Mo24} emerges as an exemplary molecular model for proton conduction and serves as a prototype for humidity gradient‐based power generators (HGPGs). The Te4Mo24‐PVDF‐based HGPG (PVDF=Poly(vinylidene fluoride)) exhibits notable stability and power generation, yielding an open‐circuit voltage of 0.51 V and a current density of 77.8 nA cm−2 at room temperature and 90 % relative humidity (RH). Further insights into the interactions between water molecules and microscale molecules within the generator are achieved through molecular dynamics simulations. This endeavor unveils a universal strategy for synthesizing multifunctional integration molecules.

AbstractElectrochemical sulfion oxidation reaction (SOR) offers a sustainable strategy for sulfion‐rich wastewater treatment, which can couple with cathodic hydrogen evolution reaction (HER) for energy‐saving hydrogen production. However, the corrosion and passivation of sulfur species render the inferior catalytic SOR performance, and the oxidation product, polysulfide, requires further acidification to recover cheap elementary sulfur. Here, we reported an amorphous high‐entropy sulfide catalyst of CuCoNiMnCrSx nanosheets in situ growth on the nickel foam (CuCoNiMnCrSx/NF) for SOR, which achieved an ultra‐low potential of 0.25 V to afford 100 mA cm−2, and stable electrolysis at as high as 1 A cm−2 for 100 h. These were endowed by the manipulated chemical environments surrounding Cu+ sites and the constructed “soft‐acid” to “hard‐acid” adsorption/desorption sites, enabling synergistically boosted adsorption/desorption process of sulfur species during SOR. Moreover, we developed an electrochemical‐chemical tandem process to convert sulfions to value‐added thiosulfate, providing a good choice for simultaneous wastewater utilization and hydrogen production.

AbstractIn living systems, protein assemblies have essential functions, serving as structural supports, transport highways for molecular cargo, and containers of genetic material. The construction of protein assemblies, which involves control over space and time, remains a significant challenge in biotechnology. Here, we show that anionic boron clusters, 3,3′‐commo‐bis[closo‐1,2‐dicarba‐3‐cobaltadodecaborane] (COSAN−), and halogenated closo‐dodecarboranes (B12X122−, X=H, Cl, or I), described as super‐chaotropic nano‐ions, induce the formation of 2D assemblies of model proteins, myoglobin, carbonic anhydrase, and trypsin inhibitor. We found that the nano‐ion concentration reversibly controls the size of the protein assemblies. Furthermore, the secondary structures of the proteins are only slightly affected by assembly formation. For myoglobin, the formation of these assemblies even prevents temperature denaturation, highlighting a preservation effect of nano‐ions. Our study reveals that inorganic boron‐based nano‐ions act as a reversible molecular glue for proteins, providing a potential starting point for the further development of controlled protein assemblies.

AbstractThermally‐induced dehydrogenative coupling of polyphenylenes on metal surfaces is an important technique to synthesize
‐conjugated carbon nanostructures with atomic precision. However, this protocol has rarely been utilized to fabricate structurally defined carbon nanosheets composed of sp‐ and sp2‐hybridized carbon atoms. Here, we present the synthesis of butadiyne‐linked hexabenzocoronenes (HBCs) on Au(111) surfaces as core‐expanded graphdiynes. The reaction started from hexa(4‐ethylphenyl)benzene, which undergoes dehydrogenation toward hexa(4‐vinylphenyl)benzene, followed by planarization to hexabenzocoronene, coupling between the vinyl groups, and further dehydrogenation. In addition to butadiyne linkages, benzene groups were also found as another type of linker. The reaction sequences were monitored by scanning tunneling microscopy and bond‐resolved non‐contact atomic force microscopy, which disclose the structures of intermediates and final products. In combination with density functional theory simulations, the key steps from ethyl substituents to butadiyne and benzene linkers were elucidated. This is a new on‐surface synthesis of core‐expanded graphdiynes with unprecedented electronic properties.

AbstractThis preliminary study sought to assess biomarkers of attention using electroencephalography (EEG) and eye tracking in two ultra‐rare monogenic populations associated with autism spectrum disorder (ASD). Relative to idiopathic ASD (n = 12) and neurotypical comparison (n = 49) groups, divergent attention profiles were observed for the monogenic groups, such that individuals with DYRK1A (n = 9) exhibited diminished auditory attention condition differences during an oddball EEG paradigm whereas individuals with SCN2A (n = 5) exhibited diminished visual attention condition differences noted by eye gaze tracking when viewing social interactions. Findings provide initial support for alignment of auditory and visual attention markers in idiopathic ASD and neurotypical development but not monogenic groups. These results support ongoing efforts to develop translational ASD biomarkers within the attention domain.

Published: July 2024

AbstractSingle‐crystalline (SC) Li‐rich layered oxides have garnered significant attention due to their inhibited lattice oxygen release and reduced crack formation compared with polycrystalline (PC) counterparts. However, it raises a crucial question regarding the selection of prevailing lithium sources‐Li2CO3 and LiOH⋅H2O‐for the solid‐state synthesis of SC cathodes, which critically impacts the technical route and future development of SC materials. Herein, a series of SC Li‐rich layered cathodes were synthesized using these two lithium sources. The SC materials prepared with LiOH⋅H2O (LRO‐H) exhibited larger grain sizes compared with those using Li2CO3 (LRO‐C). This can be attributed to the lower phase transition temperature of the precursor to spinel phase, which promotes further SC growth during solid‐state reactions. Furthermore, LRO‐H demonstrated excellent electrochemical stability, whereas LRO‐C exhibited superior initial capacities. To balance these attributes, a mixed lithium sources system (LRO‐M) was proposed, showing superior Li+ diffusion kinetics and suppressed layered‐to‐spinel transformation, resulting in excellent rate performance and an extended battery lifespan. Altogether, these findings provide critical insights into the impact of lithium sources on the growth process, structural stability, and electrochemical properties of SC Li‐rich layered cathodes, guiding the synthesis and design of next‐generation cathode materials.
