【摘要】 三芳胺衍生物是一种重要的电致变色材料,它们的电致变色通常是在四丁基高氯酸胺和四丁基高氯酸锂等盐类电解质中实现.这里,我们合成了含三芳胺的聚酰胺酸,在酸性电解质对甲苯磺酸中研究了其电致变色性能。结果表明,在对甲苯磺酸/乙腈电解质溶液中,聚酰胺酸膜及器件均展现出良好的稳定性和可逆的电致变色性能,颜色从初始状态的浅黄色转变成氧化态时的绿色。这些聚合物在酸性电解质中展现出的优异电致变色性能,使得它们在电致变色器件方面有着良好的应用前景。更多还原

【Abstract】 The electrochromism of triphenylamine derivatives is usually achieved in electrolyte containing salts such as tetrabutylammonium perchlorate and Lithium perchlorate. Here, novel poly(amide acid)s(PAA) containing triphenylamine are prepared and electrochromic properties are studied in 4-Toluene sulfonic acid(MBSA) electrolyte. The obtained PAAs have good solubility in polar organic solvents. Both of the PAA films and devices exhibite very stable and reversible electrochromic properties, changing color from the pale yellow neutral state to the green oxidized state. These remarkable electochromic performance in acid electrolyte render these electrochromic materials excellent candidates for applications in electrochromic devices.更多还原
