Highly Efficient Deep‐Blue Emitters Based on cis and trans N‐Heterocyclic Carbene PtII Acetylide Complexes: Synthesis, Photophysical Properties, and Mechanistic Studies
Authors: Zhang Yuzhen , Blacque Olivier , Venkatesan Koushik 
Published: October 2013

AbstractWe have synthesized cis and trans N‐heterocyclic carbene (NHC) platinum(II) complexes bearing σ‐alkynyl ancillary ligands, namely [Pt(dbim)2(CCR)2] [DBIM=N,N′‐didodecylbenzimidazoline‐2‐ylidene; R=C6H4F (4), C6H5 (5), C6H2(OMe)3 (6), C4H3S (7), and C6H4CCC6H5 (8)] and [Pt(ibim)2(CCC6H5)2] (9) (ibim=N,N′‐diisopropylbenzimidazoline‐2‐ylidene), starting from [Pt(cod)(CCR)2] (COD=cyclooctadiene) and 2 equivalents of [dbimH]Br ([ibimH]Br for complexes 9) in the presence of tBuOK and THF. Mechanistic investigations aimed at uncovering the cis to trans isomerization reaction have been performed on the representative cis complex 5 a [Pt(dbim)2(CCC6H5)2] and revealed the isomerization to progress smoothly in good yield when 5 a was treated with catalytic amounts of [Pt(cod)(CCR)2] at 75 °C in THF or when 5 a was heated at 200 °C in the solid state under an inert atmosphere. Detailed examination of the reactions points to the possible involvement, in a catalytic fashion, of a solvent‐stabilized PtII dialkyne complex in the former case and a Pt0 NHC complex in the latter case, for the transformation of the cis isomer to the corresponding trans complex. Thermal stability and the isomerization process in the solid state have been further investigated on the basis of TGA and DSC measurements. X‐ray diffraction studies have been carried out to confirm the solid‐state structures of 4 b, 5 a, 5 b, and 9 b. All of the synthesized dialkyne complexes 4–9 exhibit phosphorescence in solution, in the solid state at room temperature (RT), and also in frozen solvent glasses at 77 K. The emission wavelengths and quantum yields have been found to be highly tunable as a function of the alkynyl ligand. In particular, the trans isomer of complex 9 in a spin‐coated film (10 wt % in poly(methyl methacrylate), PMMA) exhibits a high phosphorescence quantum yield of 80 %, which is the highest reported for PtII‐based deep‐blue emitters. Experimental observations and time‐dependent density functional theory (TD‐DFT) calculations are strongly indicative of the emission being mainly governed by metal‐perturbed interligand (3IL) charge transfer.
Synthesis of an Orthogonal Topological Analogue of Helicene

Published: October 2013

AbstractThe synthesis of an orthogonal topological pentamer analogue of helicene is presented. This analogue forms a tubular structure with its aromatic systems directed parallel to the axis of propagation, which creates a cavity with the potential to function as a host molecule. The synthetic strategy reported, based on a series of repeating Friedländer condensations that utilize pyrido[3,2‐d]pyrimidine moieties as protected amino aldehydes, allows for the facile access of higher generations of helical, tubular structures. As a result of the synthetic strategy, only a helical isomer of the pentamer is possible. The structure and absolute configuration of the pentamer were elucidated from a combination of NMR spectroscopic data, optical properties, X‐ray structures, and by comparison of an experimental electronic circular dichroism spectrum to a calculated spectrum.
Asymmetric C(sp2)H Activation
Authors: Wencel‐Delord Joanna , Colobert Françoise 
Published: October 2013

AbstractA “niche” topic in the past decade, the asymmetric CH bond activation has been attracting growing interest over the last few years. Particularly significant advances have been achieved in the field of direct, stereoselective transformations of C(sp2)H bonds. This Concept article intends to showcase different types of asymmetric C(sp2)H bond activation reactions, emphasising both the nature of the stereo‐discriminating step and the variability of valuable scaffolds that could be rapidly constructed by means of such strategies.
Synthesis and Transistor Properties of Asymmetric Oligothiophenes: Relationship between Molecular Structure and Device Performance

AbstractA series of three thiophene–naphthalene‐based asymmetric oligomers—5‐decyl‐2,2′:5′,2′′:5′′,2′′′‐quaterthiophene (DtT), 5‐decyl‐5′′‐(naphthalen‐2‐yl)‐2,2′:5′,2′′‐terthiophene (D3TN), and 5‐(4‐decylphenyl)‐5′‐(naphthalen‐2‐yl)‐2,2′‐bithiophene (DP2TN)—was synthesized by Suzuki cross‐coupling reactions. The long alkyl side chains improved both the solubility of the oligomers in solvents and their tendency to self‐assemble. UV/Vis absorption measurements suggested that DtT, D3TN, and DP2TN form H‐type aggregates with a face‐to‐face packing structure. In addition, the three oligomers were found to adopt vertically aligned crystalline structures in films deposited on substrates, as revealed by grazing‐incidence wide‐angle X‐ray scattering. These oligomers were used as the active layers of p‐type organic field‐effect transistors, and the resulting devices showed field‐effect mobilities of 3.3×10−3 cm2 V−1 s−1 for DtT, 1.6×10−2 cm2 V−1 s−1 for D3TN, and 3.7×10−2 cm2 V−1 s−1 for DP2TN. The differences in transistor performances were attributed to the degree of π overlap and the morphological differences determined by the molecular structures.
Size‐ and Orientation‐Selective Encapsulation of C70 by Cycloparaphenylenes

Published: October 2013

AbstractThe size‐ and orientation‐selective formation of the shortest‐possible C70 peapod in solution and in the solid state by using the shortest structural unit of an “armchair” carbon nanotube (CNT), cycloparaphenylene (CPP), has been studied. [10]CPP and [11]CPP exothermically formed 1:1 complexes with C70, thereby giving the resulting peapods. A van′t Hoff plot analysis revealed that the formation of these complexes in 1,2‐dichlorobenzene was mainly driven by entropy, whereas the theoretical calculations suggested that the formation of the complex in the gas phase was predominantly driven by enthalpy. C70 was found to exist in two distinct orientations inside the CPP cavity, namely “lying” and “standing”, depending on the specific size of the CPP. The theoretical calculations and the X‐ray crystallographic analysis revealed that the interactions between [10]CPP and the short axis of C70 in its lying orientation were isotropic and similar to those observed between [10]CPP and C60. However, the interactions between [11]CPP and C70 in its standing orientation were anisotropic, thereby involving the radial deformation of [11]CPP into an ellipsoidal shape. This “induced fit” maximized the van der Waals interactions with the long axis of C70. Theoretical calculations revealed that the deformation occurred readily with low energy loss, thus suggesting that CPPs are highly radially elastic molecules. These results also indicate that the same type of radial deformation should occur in CNT peapods that encapsulate anisotropic fullerenes.
Probing DNA Mismatched and Bulged Structures by Using 19F NMR Spectroscopy and Oligodeoxynucleotides with an 19F‐Labeled Nucleobase

Published: October 2013

AbstractIn this study, DNA local structures with bulged bases and mismatched base pairs as well as ordinary full‐matched base pairs by using 19F NMR spectroscopy with 19F‐labeled oligodeoxynucleotides (ODNs) were monitored. The chemical shift change in the 19F NMR spectra allowed discrimination of the DNA structures. Two types of ODNs possessing the bis(trifluoromethyl)benzene unit (F‐unit) at specified uridines were prepared and hybridized with their complementary or noncomplementary strands to form matched, mismatched, or bulged duplexes. By using ODN F1, in which an F‐unit was connected directly to a propargyl amine‐substituted uridine, three local structures, that is, full‐matched, G–U mismatch, and A‐bulge could be analyzed, whereas other structures could not be discriminated. A molecular modeling study revealed that the F‐unit in ODN F1 interacted little with the nucleobases and sugar backbone of the opposite strand because the linker length between the F‐unit and the uridine base was too short. Therefore, the capacity of ODN F1 to discriminate the DNA local structures was limited. Thus, ODN F2 was designed to improve this system; aminobenzoic acid was inserted between the F‐unit and uridine base so the F‐unit could interact more closely with the opposite strand. Eventually, the G‐bulge and T–U mismatch and the three aforementioned local structures could be discriminated by using ODN F2. In addition, the dissociation processes of these duplexes could be monitored concurrently by 19F NMR spectroscopy.
Nickel‐Catalyzed Arylation, Alkenylation, and Alkynylation of Unprotected Thioglycosides at Room Temperature
Authors: Brachet Etienne , Brion Jean‐Daniel , Alami Mouad , Messaoudi Samir 
Published: October 2013

AbstractUnprotected thioglycosides were effective nucleophiles for Ni0‐catalyzed CS bond‐forming reaction with functionalized (hetero)aryl, alkenyl, and alkynyl halides. The functional‐group tolerance on the electrophilic partner was typically high and the anomeric selectivities of the thioglycosides were high in all cases. The efficiency of this general procedure was well‐demonstrated by the synthesis of 4‐methyl‐7‐thioumbelliferyl‐β‐D‐cellobioside (MUS‐CB).
Conversion between Difluorocarbene and Difluoromethylene Ylide

Published: October 2013

AbstractThe interconversion between difluoromethylene ylide and difluorocarbene is described. The difluoromethylene ylide precursor, Ph3P+CF2CO2−, could be turned into an efficient difluorocarbene reagent, whereas the classical difluorocarbene reagents, HCF2Cl and FSO2CF2CO2TMS, could generate highly reactive difluoromethylene ylide. Thus the Wittig difluoro‐olefination and difluorocyclopropanation could be selectively realized by using the same reagent. In addition, the ylides obtained from different carbene sources showed different reactivity in Wittig reactions.
