Synthesis and photophysical properties of semiconductor molecules D1-A-D2-A-D1-type structure based on derivatives of quinoxaline and dithienosilole for organics solar cells
PC71BM as acceptor for the fabrication solution processed bulk heterojunction solarcells for efficient exciton dissociation and high opencircuitvoltage. The organicsolarcells based on optimized DTS(QxHT2)2:PC71BM active layers processed with chloroform and DIO/CF showed overall power conversion efficiency of 3.16% and 6.30%, respectively. The higher power conversion efficiency of the solarcell based

Two copolymers having D‐A‐D‐A (P1) and D‐A (P2) structures with quinoxaline acceptor unit and dithienosilole donor unit were synthesized and their optical and electrochemical (both experimental and theoretical) properties were investigated. The optical properties showed that these copolymers P1 and P2 exhibit optical bandgaps of 1.54 and 1.62 eV, respectively, with broader absorption profiles extending

σ–π and p–π conjugation induced NIR-emitting iridium(<scp>iii</scp>) complexes anchored by flexible side chains in a rigid dibenzo[<i>a</i>,<i>c</i>]phenazine moiety and their application in highly efficient solution-processable NIR-emitting devices
photoluminescence (PL) and electroluminescence (EL) properties, and to obtain high-efficiency near-infrared (NIR)-emitting iridium(III) complexes, in this work, two rigid C^N ligands of dibenzo[a,c]phenazine (DBPz) derivatives, respectively, anchored by flexible sidechains of n-octyl and n-octyloxy and their corresponding iridium(III) complexes of Ir-R and Ir-OR were designed and synthesized. Their photophysical
