π‐conjugated electrochromic polymer (ECP) with alkyl ester side‐chains is synthesized and subsequently defunctionalized to yield a polyionic salt readily soluble in water and further spray‐processable from water. Upon neutralization, the defunctionalized polymer backbone recovers its electrochromic properties. The ability to print‐ or spray‐process π‐conjugated ECPs from aqueous media offers a sustainable
合成了具有烷基酯侧链的π共轭电致变色聚合物(ECP),然后将其去官能化,生成易溶于水且可从水中进一步喷雾加工的聚离子盐。中和后,去官能化的聚合物主链恢复其电致变色性质。从水性介质中印刷或喷涂π共轭ECP的能力为传统有机溶剂加工方法提供了可持续的替代方法,并可能影响非发射柔性显示技术的发展。
