In this study, a new copolymer, which is a combination of two chemical structure (9,10-di(furan-2-yl)anthracene and 3,4-ethylenedioxythiophene was synthesized via electrochemical synthesis methods in the electrolyte medium of 0.1 M TBAPF/ACN solution. PEDOT homopolymer was also electrosynthesized for comparator experiments of the polymer formations in the same medium. The characterizations of polymers were achieved with general optical and electrochemical characterization techniques. The corresponding electrochromic copolymer shows blue and lilac color in its neutral and oxidized states, respectively. The copolymer has an optical band gap of 1.65 eV and 24% optical contrast at 500 nm with a high coloration efficiency (170 cm /C) and a fast switching time (1.0 s).

在本研究中，一种新型共聚物通过电化学合成方法在0.1 M四丁基铵六氟磷酸盐/乙腈（TBAPF/ACN）溶液的电解质介质中合成，该共聚物由两种化学结构（9,10-二（呋喃-2-基）蒽和3,4-亚乙基二氧噻吩）组合而成。还在相同介质中电合成了聚3,4-乙撑二氧噻吩（PEDOT）均聚物，用于聚合物形成的对比实验。通过常规光学和电化学表征技术对聚合物进行表征。相应的电致变色共聚物在其中性和氧化状态下分别呈现蓝色和淡紫色。该共聚物的光学带隙为1.65 eV，在500 nm处具有24%的光学对比度，具有高显色效率（170 cm²/C）和快速切换时间（1.0 s）。
