  摘要：

  制备了具有不同聚合度的共轭噻吩偶氮甲烷。分子量和多分散指数都与阶跃生长聚合反应一致，而不是预期的通过反式消解进行动态成分交换。研究发现，中性化合物的吸光度可根据其共轭程度在 450 至 630 纳米之间进行调节。此外，还发现氧化态的吸光度随结构的变化而在 490 纳米和 1111 纳米之间变化。在溶液中对共轭偶氮亚甲基的电致变色特性进行了评估。在环境条件下，电致变色装置可以实现从可见光到近红外的颜色切换。

  Conjugated thiophene azomethines with different degrees of polymerization were prepared. Both the molecular weights and polydispersity indices were consistent with step-growth polymerization instead of the expected dynamic component exchange by transimination. It was found that the absorbance of the neutral compounds could be tuned between 450 and 630 nm, contingent on their degree of conjugation. The absorbance of the oxidized state was also found to vary between 490 nm and 1111 nm as a function of structure. The electrochromic properties of the conjugated azomethines were assessed in solution. An electrochromic device was prepared from one of the polyazomethines and it was switched between blue and colorless states with a bias of ±2 V. Visible-to-NIR color switching of the electrochromic device was possible under ambient conditions.
