systematically. Not only the dual‐electrochromic‐polymer–electrode system, but also the expanded alkylenedioxy ring in the BueDOT backbone, synergistically improved the electrochromic performance. From the coloration efficiency (CE) value calculations, we found that the CE was enhanced up to 930 cm2 C−1. Furthermore, these ECDs showed an extremely fast response time of less than 80 ms.

水性熔融盐电解质组成的新型双聚合物电致变色器件(
ECD)已被开发发达。为了构建该系统,将BueDOT主链中的亚烷基二氧基环扩展为包括一个强供电子的亚烷基二氧基桥,并系统地控制了相应PBueDOT膜的厚度和表面形态。不仅双电致变色聚合物-电极系统,而且BueDOT主链中的扩展亚烷基二氧基环均协同改善了电致变色性能。从着色效率(CE)值计算,我们发现CE增强到930 cm 2 C -1。此外,这些
ECD的响应时间极短,不到80 ms。
