Synthesis of a novel macroinimer comprising poly(ε‐caprolactone) (PCL) and thiophene (Th) and its use in electrochromic device (ECD) application have been reported. First, a novel Th monomer (5) with miktofuntional initiator groups (primary hydroxyl and tertiary bromide at the third position of the thiophene ring) was synthesized in a four‐step reaction sequence.

已经报道了包含聚(ε-己内酯)(PCL)和噻吩(Th)的新型大分子单体的合成及其在电致变色器件(ECD)应用中的用途。首先,以四步反应顺序合成了具有功能泛函引发剂基团(在噻吩环的第三位的伯羟基和叔溴化物)的新型Th单体(5)。密度泛函理论预测的键长,角度和振动为5,与可用的实验振动光谱非常吻合。随后,使用5作为引发剂和2-乙基己酸锡(II)(Sn(Oct)2)作为催化剂在115°C下的反应,这导致了α-噻吩封端的PCL大分子单体(PCL-Th)。此外,PCL-Th大分子单体还用于与吡咯(Py)和Th的电化学共聚。在氧化铟锡涂层的玻璃载玻片上合成的PCL-Th / PTh共聚物薄膜表现出电致变色行为。对PCL-Th / PTh共聚物薄膜的光学分析表明,该共聚物薄膜适合用作ECD应用的阳极着色材料。©2011 Wiley Periodicals,Inc.
