Aqueous zinc-ion batteries (AZIBs) have attracted interest for their low cost and environmental friendliness. Two bipolar organic materials with different degrees of conjugation, pPMQT pNTQT, were rationally designed synthesized as cathode candidates AZIBs based on 4,4′-diaminotriphenylamine (TPA), 2,7-diaminoanthraquinone (AQ), two anhydrides. This molecular design features an increased conjugation electron cloud density, thereby improving charge transport kinetics, specific capacity, cycling stability. In comparison pPMQ pNTQ (n-type), pNTQT demonstrate better electrochemical characteristics. this work, shows outstanding performance. It exhibits initial capacity 349.79 mAh g−1 at 0.1 A retains a 190.25 (87.6%) after 5000 cycles 5 g−1. comparison, demonstrates only 207.55 g−1, its retention rate is 81.2%. At the same time, both polymer films attractive electrochromic (EC) properties, displaying reversible color transitions from yellow to dark blue in UV–visible spectrum. work lays foundation further development triphenylamine-based polyimide application electrochromism.
