Herein, a post\u2010polymerization modification strategy is used to prepare a series of reactive azo\u2010LCPs using the trans\u2010esterification reaction of poly(pentafluorophenyl acrylate) with functional alcohols. These reactive azo\u2010LCPs show good capabilities in fabricating fibers via a simple thermal\u2010drawing method and subsequent crosslinking reaction with diamine under mild conditions. Furthermore, the prepared fibers exhibit reversible deformation behaviors under the alternate irradiation of UV and visible light (365\/530\u2009nm). This facile synthetic strategy is expected to open up new possibilities for fabricating photo\u2010driven actuators.<\/jats:p><\/jats:sec>","DOI":"10.1002\/aisy.202000254","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T12:06:43Z","timestamp":1616414803000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["A Convenient Route to Prepare Reactive Azobenzene\u2010Containing Liquid Crystal Polymers and Photodeformable Fibers"],"prefix":"10.1002","volume":"3","author":[{"given":"Yan","family":"Chen","sequence":"first","affiliation":[{"name":"Department of Materials Science and State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}]},{"given":"Quan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Materials Science and State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}]},{"given":"Patrick","family":"Theato","sequence":"additional","affiliation":[{"name":"Soft Matter Synthesis Laboratory, Institute for Biological Interfaces III (IBG3) Karlsruhe Institute of Technology (KIT)  Hermann-von-Helmholtz-Platz 1 D-76344 Eggenstein-Leopoldshafen Germany"}]},{"given":"Jia","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Materials Science and State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4623-3331","authenticated-orcid":false,"given":"Yanlei","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Materials Science and State Key Laboratory of Molecular Engineering of Polymers Fudan University  220 Handan Road Shanghai 200433 China"}]}],"member":"311","published-online":{"date-parts":[[2021,3,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.200304552"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/adma.201806849"},{"key":"e_1_2_6_4_1","first-page":"8","volume":"30","author":"Pang X.","year":"2020","journal-title":"Adv.
