Abstract A monomer named 2-(Anthracen-9-yl)thiophene (An-Th) has been synthesized via Stille coupling reaction, while its homopolymer is difficult to prepare on the conducting electrode via electrochemical methods. However, it can be a good comonomer to obtain copolymers with other monomers such as thiophene (Th), selenophone (SePh), 3-methylthiophene (MeTh) and 3,4-ethylenethiophene (EDOT) via electrochemical copolymerization. The structures of the prepared copolymers are characterized via FTIR and XPS analysis. In addition, the spectroelectrochemical and electrochromic properties of these copolymers are also investigated. The derived copolymers present multicolor electrochromism, which can be tuned by the applied comonomer and polymerization solvent. Moreover, the copolymers have reasonable switching response and stability. All of these indicate that the synthesized Th-An can be applied as a good comonomer for preparation of electrochromic copolymers.

基于 2-（蒽-9-基）噻吩的共聚物的电化学合成：一系列多色电致变色聚合物的简便有效途径

摘要 通过Stille偶联反应合成了一种单体2-(Anthracen-9-yl)噻吩(An-Th)，但其均聚物难以通过电化学方法在导电电极上制备。然而，通过电化学共聚获得与其他单体如噻吩 (Th)、硒酚 (SePh)、3-甲基噻吩 (MeTh) 和 3,4- 乙撑噻吩 (EDOT) 的共聚物可能是一种很好的共聚单体。通过FTIR和XPS分析表征所制备共聚物的结构。此外，还研究了这些共聚物的光谱电化学和电致变色性能。衍生的共聚物呈现多色电致变色，可通过应用的共聚单体和聚合溶剂进行调节。此外，共聚物具有合理的切换响应和稳定性。
