The porous structure produced by star-shaped molecules via electrochemical polymerization provides a number of transport channels, which will be beneficial for ions migration and improving electrochemical and electrochromic performance. Two novel star-shaped trithiophene and hexathiophene functionalized truxenes, Tr-3Th and Tr-6Th, were successfully synthesized. The corresponding porous polymers PTr-3Th and PTr-6Th, prepared by the electrochemical polymerization of the Tr-3Th and Tr-6Th, have provided compatible ion transport channels, which performed high electrochemical stability (maintain 99% electrochemical activity after 5000 cycles). PTr-3Th revealed colour change from light gray-green to dark gray-green upon oxidation, meanwhile, PTr-6Th presented the colour variations from light yellow to green. The result provides a new insight into the design of electrochromic polymers with good stability.

所产生的多孔结构星形分子通过电化学聚合提供了许多传输通道，这将有利于离子迁移并改善电化学和电致变色性能。成功合成了两种新颖的星形三噻吩和六噻吩官能化的丁烯，即Tr-3Th和Tr-6Th。通过Tr-3Th和Tr-6Th的电化学聚合制备的相应多孔聚合物PTr-3Th和PTr-6Th提供了兼容的离子传输通道，该通道具有很高的电化学稳定性（5000次循环后保持99％的电化学活性）。PTr-3Th氧化后颜色从浅灰绿色变为深灰绿色，而PTr-6Th呈现颜色从浅黄色变为绿色。结果为具有良好稳定性的电致变色聚合物的设计提供了新的见识。
