Herein, azobenzenemolecules into polyurethane elastomer containing crystalline structure for preparing azobenzene liquid\u2010crystal elastomers (ALCEs) are demonstrated and this phenomenon of the synergistic effects between liquid crystal and crystalline phase is discovered. The key point of the work is that the synthetic ALCEs can utilize the reversible isomerism capability of azobenzene molecules under light irradiation, which can pry the motion of the macromolecular crystalline region in system to realize the large macroscopic deformation of the photo\u2010responsive behavior. Obviously, the ALCEs sample containing azobenzene molecule and polyethylene glycol crystallization can quickly bend, illuminated by ultraviolet light and rapidly straighten under green light. Under the same ultraviolet irradiation, the bending speed, final bending angle, recovery rate and recovery ratio of ALCEs are larger than that of ALCEs without any crystalline structure. This ALCEs based on the synergistic effects between liquid crystal and crystalline phase can break through the current dilemma that the application of traditional azobenzene photo\u2010responsive materials is limited by their concentration, greatly expanding the design thought and their scope of application.<\/jats:p>","DOI":"10.1002\/marc.202300354","type":"journal-article","created":{"date-parts":[[2023,8,12]],"date-time":"2023-08-12T13:13:07Z","timestamp":1691845987000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Synergistic Effects between Liquid Crystal and Crystalline Phase on Photo\u2010Responsive Elastomers toward Quick Photo\u2010Responsive Performance"],"prefix":"10.1002","volume":"44","author":[{"given":"Xudong","family":"Wu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Polymer Materials Engineering Polymer Research Institute of Sichuan University  Chengdu 610065 P.
