The solid\u2010state features of the monomers were elucidated by single crystal X\u2010ray diffraction, revealing the presence of C\u2500H\u00b7\u00b7\u00b7X (X\u00a0=\u00a0O\/N\/F), C\u2500X\u00b7\u00b7\u00b7\u03c0 (X\u00a0=\u00a0H\/O) and \u03c0\u00b7\u00b7\u00b7\u03c0 interactions. Hirshfeld surface and energy framework analysis further demonstrated that dispersion interactions are the dominant contributor to the overall crystal packing. Thermal analysis of the acrylate and 2\u2010fluoroacrylate based monomer indicated the presence of nematic mesophase over a narrow temperature window (1\u00b0C\u20132\u00b0C), whereas the methacrylate\u2010terminated monomers did not display liquid crystalline behavior. In contrast, polymerization resulted in a significantly broadened nematic mesophase range exceeding 70\u00b0C, highlighting the critical role of the polymer backbone in mesophase stabilization. Further, the monomers displayed photoinduced nematic\u2010isotropic phase transition upon irradiation with 365\u00a0nm UV light. Additionally, the monomers and polymers exhibited reversible\n                    <jats:italic>trans<\/jats:italic>\n                    <jats:italic>cis<\/jats:italic>\n                    isomerization in solution under 365\u00a0nm UV and 510\u00a0nm visible light irradiation, achieving up to 90% conversion efficiency. These findings underscore the role of the polymer backbone in promoting liquid crystallinity and photoresponse toward the development of stimuli\u2010responsive materials.\n                  <\/jats:p>","DOI":"10.1002\/chem.71326","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T04:14:31Z","timestamp":1782447271000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Polymerization\u2010Induced Liquid Crystallinity With Broadened Mesophase Temperature Range in Side\u2010Chain Polymers Incorporating Photoresponsive 4\u2010Cyanoazobenzene Units"],"prefix":"10.1002","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-7662-2244","authenticated-orcid":false,"given":"Omkar","family":"Dash","sequence":"first","affiliation":[{"name":"Department of Chemistry Visvesvaraya National Institute of Technology  Nagpur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jyoti Swarup","family":"Thakur","sequence":"additional","affiliation":[{"name":"Department of Chemistry Visvesvaraya National Institute of Technology  Nagpur Maharashtra India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pradip Kumar","family":"Mondal","sequence":"additional","affiliation":[{"name":"S.C.p.A.
