Herein, two triphenylamine\u2212fluorene conjugated polymers, TFPA and TFPACA, are synthesized by incorporating phosphonic acid or dual phosphonic acid\/carboxylic acid anchoring groups into the polymers. This anchoring strategy strengthens polymer\/ITO interfacial interactions, enhances film adhesion, suppresses interfacial defects, and promotes more uniform charge injection and extraction during electrochemical operation. Both polymers exhibit reversible electrochromic behavior, while the dual-anchored TFPACA-based devices deliver a high optical contrast (\u0394T) of 45.08%, a coloration efficiency (CE) of 559.7 cm2 C\u22121, and excellent cycling stability, retaining 86% of the initial optical contrast after 3500 switching cycles. Building energy consumption simulations further indicate an annual energy reduction of 103,319.23 kWh, corresponding to a carbon emission reduction of approximately 51.66 kg CO2. These results highlight anchoring-induced interfacial engineering as an effective strategy for developing high-performance and durable electrochromic polymers.<\/jats:p>","DOI":"10.1021\/acsami.6c06817","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T08:02:28Z","timestamp":1790668948000},"page":"55385-55397","source":"Crossref","is-referenced-by-count":0,"title":["Anchoring-Induced Interfacial Stabilization in Triphenylamine-Based Electrochromic Polymers"],"prefix":"10.1021","volume":"18","author":[{"given":"Dongwen","family":"Zou","sequence":"first","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Cui","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunyu","family":"Wang","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hao","family":"Sun","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyang","family":"Li","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2887-735X","authenticated-orcid":true,"given":"Yaowu","family":"He","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Shantou University , , ,","place":["Shantou, China, 515063"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5877-359X","authenticated-orcid":true,"given":"Hong","family":"Meng","sequence":"additional","affiliation":[{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]},{"name":"Peking University , , ,","place":["Shenzhen, China, 518055"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,29]]},"reference":[{"issue":"4","key":"2026101408071639300_cit1","doi-asserted-by":"publisher","first-page":"1824","DOI":"10.1039\/D4EE05416D","article-title":"A Novel Liquid Flow Electrochromic Smart Window for All-Year-Round Dynamic Photothermal Regulation","volume":"18","author":"Huang","year":"2025","journal-title":"Energy Environ.
