  D?A?D low band gap molecule containing triphenylamine and benzoxadiazole/benzothiadiazole units: Synthesis and photophysical properties

  摘要：

  Two D-A-D-type low band gap organic dyes based on triphenylamine and benzoxadiazole/benzothiadiazole, 4,7-Bis{5-{4-{2-[4-(N,N-diphenylamino)phenyl]-1-nitrilethenyl}phenyl}-2-thienyl}-2,1,3-benzoxadiazole (BDNTBX) and 4,7-Bis{5-{4-{2-[4-(N,N-diphenylamino)phenyl]-1-nitrilethenyl}phenyl}-2-thienyl}-2,1,3-benzothiadiazole (BDNTBT) were successfully synthesized. The properties of two compounds were investigated by density functional theory (DFT) calculations, UV-vis absorption spectroscopy, cyclic voltammetry and fluorescence quenching experiment. The calculated ground-state geometries demonstrate intramolecular charge transfer (ICE) occurs in both molecules during the procedure of charge excitation from HOMO to LUMO. From the data in electrochemistry and fluorescence quenching experiments, the molecules reveal lower HOMO energy levels compared with that of P3HT and proper LUMO energy levels to obtain efficient charge separation with PCBM. Two synthesized compounds exhibit broad absorption range covering the whole visible spectral region. These photophysical and electrochemical properties call attention to that our materials are prospective candidates as donor materials for solution-processable organic photovoltaic cells.

  Dehydrogenations Using Benzofuroxan as Oxidant

  摘要：

  2-Arylsubstituted benzimidazoles, quinoxalines, in 3,5-position substituted 2,6-dimethylpyridines, and 1,4-bis(alkylamino)-9,10-anthracenediones are easily prepared under mild conditions by means of benzofuroxan as oxidant. Thus, the preparation of 2-arylbenzimidazoles succeeds in acetonitrile at 50-degrees-C in yields of 65 to 78 %.

• Cu-Catalyzed π-Core Evolution of Benzoxadiazoles with Diaryliodonium Salts for Regioselective Synthesis of Phenazine Scaffolds
  作者：Jinyu Sheng、Ru He、Jie Xue、Chao Wu、Juan Qiao、Chao Chen

  DOI：10.1021/acs.orglett.8b01748

  日期：2018.8.3

  The Cu-catalyzed regioselective synthesis of phenazine N-oxides was realized from benzoxadiazoles and diaryliodonium salts. The process was initiated by the electrophilic arylation of benzoxadiazoles with diaryliodonium salts and followed by benzocyclization reactions. The further reduction of N-oxides in situ to phenazine scaffolds and deviation to organic fluorescent materials were readily accomplished
