(TPA)‐containing bis(ether anhydride) monomer, namely 4,4′‐bis(3,4‐dicarboxyphenoxy)triphenylamine dianhydride, was synthesized and reacted with various aromatic diamines leading to a series of new poly(ether‐imide)s (PEI). Most of these PEIs were soluble in organic solvents and could be easily solution cast into flexible and strong films. The polymer films exhibited good thermal stability with glass‐transition
合成了一种新型的含三苯胺(TPA)的双(醚酐)单体,即4,4'-双(3,4-二羧基苯氧基)三苯胺二酐,并与各种芳族二胺反应生成了一系列新的聚(醚-酰亚胺)(PEI)。这些PEI中的大多数都可溶于有机溶剂,可以很容易地溶液流延成柔软而坚固的薄膜。聚合物膜在211–299°C的玻璃化转变温度下表现出良好的热稳定性。聚合物膜表现出可逆的电化学过程和稳定的颜色变化(从透明到海军蓝),具有高的着色效率和电氧化后的对比度。在电化学氧化过程中,由于聚合物链中TPA自由基阳离子部分之间的偶联反应,形成了交联的聚合物结构。这些聚合物可用于制造具有高着色效率,高氧化还原稳定性和快速响应时间的电致变色器件。©2013 Wiley Periodicals,Inc.
