新型的X形共轭寡噻吩，形成了一个定义明确的C4取代化合物家族，其核心噻吩环具有四个含有α -α和α -β键的短链分支，通过简单的合成路线设计和合成。它们的光电特性可以通过操纵分支的部分进行电子微调。在溶液中，四种化合物表现出较强的光致发光，最大发射波长分别为459,491,494和547 nm。其薄膜的光学性质表明在这些X形低聚物中存在有趣的共轭效应。对这些化合物进行了循环伏安测定，并通过电化学聚合制备了两种单体的稳定聚合物。研究了所得电活性聚合物的紫外可见吸收和发射特性，表明三维聚合物的光学特性可以通过重复电位扫描来控制。
Novel X‐shaped conjugated oligothiophenes, which form a family of well‐defined C4‐substituted compounds with a core thiophene ring that bears four short‐chain branches containing α–α and α–β linkages, have been designed and synthesized by a facile synthetic route. Their optoelectronic properties can be electronically fine‐tuned by manipulating the segments of the branches. In solution, the four compounds show strong photoluminescence with emission maxima located at 459, 491, 494, and 547 nm. The optical properties of their films suggest an interesting conjugated effect in these X‐shaped oligomers. Cyclic‐voltammetry measurements of these compounds have been performed, and corresponding stable polymers from two of the monomers have been prepared by electrochemical polymerization. UV–vis absorption and emission properties of the resultant electroactive polymers are studied, indicating that the optical properties of the 3D polymers could be controlled by repeated potential scans.
