Dithieno[3,2-b:2′,3′-d]pyrrole-based terthiophene and quaterthiophene analogues have been prepared from N-functionalized dithieno[3,2-b:2′,3′-d]pyrroles (DTPs) via Stille coupling. In order to thoroughly study the structure–function property relationships within these DTP-based oligothiophenes, an oligomer series was prepared that allows for the investigation of a number of structural effects including
Dithieno [3,2- b:2',3'- d ]吡咯-基于 对噻吩 和 四噻吩N-官能化的二硫杂[3,2- b:2',3'- d ]吡咯(DTP)通过Stille偶联制备了类似物。为了彻底研究其中的结构-功能特性关系DTP的低聚噻吩,制备了一种低聚物系列,可用于研究许多结构效应,包括链长, 噻吩 功能化,以及 吡咯N功能化。由于吡咯N-官能化允许掺入可溶的侧链而没有通常会降低主链平面性的有害空间相互作用,因此,已经仔细研究了这些侧链的大部分对溶液和固态两种光学性质的影响。这DTP-基于 四噻吩, ñ -叔丁基-2,6-双(2'-噻吩基)噻吩并[3,2- b:2',3'- d ]吡咯通过X射线晶体学表征,发现在单斜空间群P 2 1 / c中结晶,其中a = 17.489(4)Å,b = 7.8855(16)Å,c = 14.540(3)Å,β = 108.37 (3)°,Z =4。通过
