We report herein the design and synthesis of some novel liquid crystalline semiconductors constructed from a biologically and pharmacologically active building block molecule, namely 6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophene, presenting efficient luminescence and medium charge mobility rate. A first series of mesogenic 2-phenylbenzothiophene derivatives (nPBT) was simply and rapidly obtained in good yields by successive demethylation/alkylation reactions of the available methoxy precursor. The further stepwise oxidations moreover resulted in two new sets of the corresponding sulfoxide (nPBTO) and sulfone (nPBTO2) derivatives, respectively, that were also mesomorphic. The liquid crystalline behaviour was comprehensively characterized by DSC, POM and SAXS: all compounds exhibit smectic-like behaviour in agreement with their calamitic shape. More specifically, mesogens nPBT showed a SmA phase, with in addition, a higher ordered smectic phase at lower temperature. As for the oxidized mesogens, they displayed a SmA phase only, and over particularly large temperature ranges for the nPBTO with longer chain lengths (n ? 8). The photo-physical properties have also been studied both in solution and thin films, and the molecules were found to display strong absorption in the UV/vis domain and intense luminescence in the range of 400?650 nm (yellowish green light) in high quantum yields (up to 62%). Both absorption and luminescence were also found to be affected by the oxidation of the benzothiophene moiety. Finally, the semi-conducting behaviour of three PBT compounds in the various mesophases was investigated by photocurrent TOF technique. Hole mobility rates of ca. 4 × 10?3 cm2 V?1 s?1 were measured in the lower temperature ordered mesophase for all of them, with the best performances (temperature range and mobility values) however obtained for the shortest homolog (n = 6). With such highly reasonable mesomorphic, light-emitting and semiconducting functional features, as well as being cheap and easy to synthesize and to process, these materials become very attractive and may be incorporated into various kinds of electronic devices (OFET and OLED).

A palladium-catalyzed asymmetric carbon-carbon cleavage for the preparation of functionalized axially chiral molecules was reported. Increasing ring distortion not only enhanced the reactivity but also improved the chemoselectivity for different carbon-carbon bonds. This protocol enabled the quick synthesis of ketone-containing axially chiral biaryls in high yields and enantioselectivities.Development of new synthetic strategies for enantioselective carbon-carbon and carbon-heteroatom bond formation is one of the pillars of modern organic chemistry. Whereas significant advances have been achieved in center chirality construction, catalytically asymmetric construction of axial chirality is still under development. Moreover, axially chiral molecules constructed through carbon-carbon and carbon-heteroatom bond cleavage are extremely limited. Here, we report an asymmetric synthesis of biaryl atropisomers via palladium-catalyzed chemoselective carbon-carbon cleavage of 9-aryl-9H-fluoren-9-ols. The reaction demonstrated broad substrate scope and produced the atropisomers in high yields and enantioselectivity. The ring-opening reactivity was considerably accelerated by the torsional strain created by the steric repulsion between two ortho-substituents of the biaryl skeleton in the substrates. The high enantiocontrol hinges on the evolvement of a new TADDOL-based phosphoramidite as ligand. These findings set up a new platform for the development of novel synthetic methods via asymmetric carbon-carbon cleavage.Rapid generation of chirality to increase the complexity of molecules is pivotal for organic synthesis, material chemistry, and drug discovery. By taking advantage of ring strain, we developed a palladium-catalyzed asymmetric carbon-carbon bond cleavage reaction for facile access to a series of axially chiral biaryls in an atom-economical fashion. High functional group tolerance, yields, and enantioselectivities were achieved. The method set up a new platform toward axially chiral biaryl units found in many biologically active natural products, drugs, and catalysts. The present work also showcased a promising strategy for the activation of other non-activated molecules via increasing the ring strain by molecular distortion.

A catalytic enantioselective method for the synthesis of chiral 1H-isoindoles bearing quaternary stereogenic centers is reported. Powered by readily accessible phosphordiamidite ligands, the presented palladium(0)-catalyzed C?H functionalization uses trifluoroacetimidoyl chlorides as electrophilic components. It delivers previously inaccessible perfluoroalkylated 1H-isoindoles in high yields and enantioselectivities. The subsequent diastereoselective addition of nucleophiles provides access to densely substituted and sterically hindered isoindolines.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Read on for other articles about 5394-13-8

A mononuclear iron complex with 2-ethynylbenzo[b]thiophene C-coordinated to the (eta5-Cp*)(eta2-dppe)Fe (Cp* = pentamethylcyclopentadienyl, dppe = 1,2-diphenylphosphinoethane) framework (1) was prepared and characterized by 1H NMR, elemental analysis, and single crystal X-ray diffraction. The redox behavior of 1 was investigated by voltammetric methods and anodic spectroelectrochemistry in the UV?vis-NIR-IR region and compared with reference complexes including 2-ferrocenylbenzo[b]thiophene (2) and the 2-ethynylpyridine derivative of 1. The spin density distribution along the linear molecular backbone in 1+ was analyzed by DFT (BLYP35) and TDDFT calculations of a truncated model complex. The combined experimental and theoretical results revealed an important role of the ethynylene linker in determining the redox properties of this family of complexes and participation of the 2-ethynylbenzo[b]thiophene framework in the largely iron-based anodic electron transfer.

We report an extensive ?heteroarene scan? of triazine nitrile ligands of the cysteine protease human cathepsin L (hCatL) to investigate pi-stacking on the peptide amide bond Gly67?Gly68 at the entrance of the S3 pocket. This heteroarene???peptide bond stacking was supported by a co-crystal structure of an imidazopyridine ligand with hCatL. Inhibitory constants (Ki) are strongly influenced by the diverse nature of the heterocycles and specific interactions with the local environment of the S3 pocket. Binding affinities vary by three orders of magnitude. All heteroaromatic ligands feature enhanced binding by comparison with hydrocarbon analogues. Predicted energetic contributions from the orientation of the local dipole moments of heteroarene and peptide bond could not be confirmed. Binding of benzothienyl (Ki=4 nm) and benzothiazolyl (Ki=17 nm) ligands was enhanced by intermolecular C?S???O=C interactions (chalcogen bonding) with the backbone C=O of Asn66 in the S3 pocket. The ligands were also tested for the related enzyme rhodesain.
