To address this, we designed and synthesized two novel D-π-D structured CMPs featuring multiple redox-active centers by virtue of a π-conjugation engineering strategy via facile liquid-liquid interfacial polymerization. The resultant device achieved a high optical contrast of 54.1% at 750 nm, an improved area specific capacitance of 30.46 mF·cm<sup>−2</sup>, and a rapid switching speed (2.3 s/1.2 s), attributed to efficient intramolecular charge delocalization and rapid charge transfer kinetics, stemming from the D-π-D molecular architecture. The fabricated smart window demonstrates an effective thermal insulation performance of 14.4 °C temperature reduction versus a general glass window. Furthermore, the electric energy involved in electrochromism could be recycled to power an LED for 30 s. This work provides a viable design strategy for developing high-performance CMPs with integrated electrochromic and energy storage functions.</div></div>","PeriodicalId":351,"journal":{"name":"Journal of Colloid and Interface Science","volume":"710 ","pages":"Article 140033"},"PeriodicalIF":9.7,"publicationDate":"2026-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146130733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
