A novel dibromo compound containing unsymmetrical substituted bi‐triarylamine was synthesized. A conjugated polymer was prepared via the Suzuki coupling from the newly prepared dibromo compound and 9,9‐dioctylfluorene‐2,7‐bis(trimethyleneboronate). The glass transition temperature (Tg) of the conjugated polymer was 140 °C, 10% weight‐loss temperatures (Td10) in nitrogen was 458 °C, and char yield at
合成了一种新型的含不对称取代的联三芳基胺的二溴化合物。通过Suzuki偶联从新制备的二溴化合物和9,9-二辛基芴-2,7-双(三亚甲基硼酸酯)制备共轭聚合物。共轭聚合物的玻璃化转变温度(T g)为140°C,氮气中10%的失重温度(T d10)为458°C,氮气中800°C的炭收率高于64%。浇铸在氧化铟锡(ITO)涂层的玻璃基板上的聚合物膜的循环伏安图显示,相对于Ag / Ag +,在0.70和1.10 V时有两个可逆的氧化还原对。在乙腈溶液中。聚合物膜显示出优异的电致变色特性稳定性,在0至1.3 V的施加电势下,其颜色从中性形式的黄绿色变为氧化态的深绿色和蓝色。颜色转换时间和漂白时间分别为4.25和860 nm时为7.22 s,560 nm时为5.51 s和6.48 s。©2010 Wiley Periodicals,Inc.
