However, current electrochromic materials typically exhibit limited response speeds, which still pose a significant challenge to realizing truly dynamic display technology. In this work, we used tetrahydrofuran (THF) to induce solvation in a hydroxyl\u2010terminated side\u2010chain electrochromic polymer. The hydrogen bonds formed during this process generate induced polarization, which promotes the aligned arrangement of surrounding solvent molecules. Consequently, the uneven distribution of solvent triggers phase separation during spin\u2010coating, ultimately forming a porous electrochromic film with a high specific surface area. By constructing this multi\u2010layered porous thin film, we achieve a coloration response time of 0.87 s and a bleaching response time of 0.22 s, while maintaining a high optical contrast of 70.89% at 500\u00a0nm. Additionally, benefiting from the ability of hydrogen bonding to alleviate mechanical stress, we fabricated both active and passive display matrix prototypes on rigid and flexible substrates, achieving a fast switching rate of 0.1 s under a low operating voltage of 1.4\u00a0V (Bleaching time = 5\u00a0ms). This strategy exhibits a certain degree of generality, highlighting the potential of side\u2010chain\u2010engineered, solvent\u2010induced assembly for developing ultrafast electrochromic display materials.<\/jats:p>","DOI":"10.1002\/adma.202523062","type":"journal-article","created":{"date-parts":[[2026,8,9]],"date-time":"2026-08-09T10:01:54Z","timestamp":1786269714000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Ultrafast
