以苯胺为核心，噻吩为臂，通过铃木偶联反应成功合成了星形分子三[4-（2-噻吩基）苯基]胺。对聚三[4-（2-噻吩基）苯基]胺（PTTPA）进行了电化学合成和表征。所得聚合物薄膜在不同电位下呈现出四种不同的颜色。此外，PTTPA薄膜具有较高的光学对比度（430 nm为38%，560 nm为29%，710 nm为53%）和令人满意的响应时间（430 nm为2.57 s， 560 nm为0.76 s， 710 nm为2.10 s）。构建并表征了基于PTTPA和聚（3,4-乙烯二氧噻吩）（PEDOT）的电致变色器件（ECD）。发现该ECD具有良好的开关时间，合理的对比度，令人满意的光记忆和氧化还原稳定性。(C) 2012 Elsevier B.V.版权所有
A star-shaped molecule, tris[4-(2-thienyl)phenyl]amine, which contains phenylamine as core and thiophene as arms, was successfully synthesized via Suzuki coupling reaction. Poly(tris[4-(2-thienyl)phenyl]amine) (PTTPA) was electrochemically synthesized and characterized. The resulting polymer film exhibited four various colors under different potentials. Moreover, the PTTPA film showed high optical contrast (38% at 430 nm, 29% at 560 nm, and 53% at 710 nm) and satisfactory response time (2.57 s at 430 nm, 0.76 s at 560 nm, and 2.10 s at 710 nm). An electrochromic device (ECD) based on PTTPA and poly(3,4-ethylenedioxythiophene) (PEDOT) was also constructed and characterized. This ECD was found to have good switching times, reasonable contrast, and satisfactory optical memories and redox stability. (C) 2012 Elsevier B.V. All rights reserved.
