The synthesis, comparative physicochemical properties, and solid-state structures of five oligothiophene (nT) series differing in substituent nature and attachment, regiochemistry, and oligothiophene core length (n) are described. These five series include the following 25 compounds: (i) alpha,omega-diperfluorohexyl-nTs 1 (DFH-nTs, n = 2-6), (ii) beta,beta'-diperfluorohexyl-nTs 2 (isoDFH-nTs, n = 2-6)
描述了在取代基性质和连接、区域化学和低聚噻吩核心长度 (n) 方面不同的五个低聚噻吩 (nT) 系列的合成、比较物理化学性质和固态结构。这五个系列包括以下 25 种化合物:(i) alpha,omega-diperfluorohexyl-nTs 1 (DFH-nTs, n = 2-6), (ii) beta,beta'-diperfluorohexyl-nTs 2 (isoDFH-nTs, n = 2-6), (iii) α,omega-二己基-nTs 3 (DH-nTs, n = 2-6), (iv) β,β'-二己基-nTs 4 (isoDH-nTs, n = 2- 6),和 (v) 未取代的低聚噻吩 5(alphanTs,n = 2-6)。所有新化合物均通过元素分析、质谱和多核 NMR 光谱进行表征。为了定量地探讨和解决共轭核取代的化学和区域化学如何影响分子和固态特性,通过差示扫描量
