使用氯化铁作为催化剂,通过区域选择性的Scholl反应,由聚芳基噻吩设计并合成了一系列的噻吩噻吩。这些杂芳烃的分子结构显示出多个扭曲的峡湾,扰乱了多环骨架的形状,以平行或反平行堆积的方式滑移至接近完美的面对面样式。使用6,12-二氟联菲[9,10-b:9',10']噻吩单晶的场效应晶体管器件的空穴迁移率为0.22 cm 2 V -1 s -1。
successful programmed synthesis of diversedesigns of tetraphenylthiophene derivatives (TPTs, 16 out of 24 probable structures) and the intermediate triphenylthiophene derivatives (12 out of 20 probable structures) using optimized ‘classical’ Suzuki-Miyaura cross-coupling conditions through multiple routes starting from a single precursor, tetrabromothiophene. Our first-ever electrochemical analysis of various
Tetraarylthiophenes were prepared by regioselective Suzuki cross-coupling reactions of tetrabromothiophene. (c) 2006 Elsevier Ltd. All rights reserved.
