Enhancing switching response capability of electrochromic (EC) polymers has been a topical issue. Herein, the H-shaped nonplanar pentiptycene scaffold is successfully introduced into the polyamide film derived from N,N'-bis(4-aminophenyl)-N,N'-di(methoxyphenyl)-1,4-phenylenediamine (TPPA), and the resulting copolymer shows enhanced EC behaviors, including lower oxidation potential and shorter switching response time, as compared to the corresponding TPPA-derived homopolymer.
提高电致变色(EC)聚合物的开关响应能力一直是一个热门话题。本文将 H 型非平面五并苯骨架成功引入到由 N,N'-双(4-氨基苯基)-N,N'-二(甲氧基苯基)-1,4-苯二胺(TPPA)衍生的聚酰胺薄膜中,所得共聚物表现出增强的 EC 行为,与相应的 TPPA 衍生的均聚物相比,其氧化电位更低,开关响应时间更短。
