We report on poly(arylene-imidazoliums), which were synthesized by microwave polycondensation of dialdehyde with bisbenzil and quantitatively functionalized by alkylation. This cationic polyelectrolyte is sterically protected around the C2-position and is stable in 10 M KOH_aq at 100 °C (t_1/2 of >5000 h). Alkaline stability is rationalized through analyses of model compounds, single crystal X-ray diffraction, and density functional theory. The polyelectrolytes form tough, pliable, transparent, ionically conductive films.

阳离子聚电解质，在 100 °C 下在 10 M KOHaq 中稳定

我们报告了聚（亚芳基 - 咪唑），它是通过二醛与双苄基的微波缩聚合成并通过烷基化定量功能化的。这种阳离子聚电解质在 C2 位周围受到空间保护，并且在 100 °C的 10 M KOH_{水溶液中是稳定的（} t _1/2 of >5000 h）。通过对模型化合物、单晶 X 射线衍射和密度泛函理论的分析，使碱性稳定性合理化。聚电解质形成坚韧、柔韧、透明、离子导电的薄膜。
