Herein, we investigate the grafting of coumarin-containing promesogenic moieties to pillar[5]arene as a strategy to obtain multifunctional LCMs. Pillar[5]arenes containing 10 and 30 coumarin units are glassy materials with nematic mesomorphism. Moreover, the coumarin moieties afford the pillar[5]arene derivatives with enhanced film-forming and photoresponsive properties. Photodimerization of the coumarin moieties results in cross-linked polymer networks, which can be used as alignment layers. Therefore, liquid-crystal coumarin-containing pillar[5]arenes represent a significant addition to the family of LCMs and may become useful for the development of engineered, hierarchical structures and materials.2020http://zaguan.unizar.es/record/10615410.1021/acs.joc.0c00852http://zaguan.unizar.es/record/106154oai:zaguan.unizar.es:106154info:eu-repo/grantAgreement/ES/DGA-FEDER/LMP150-18info:eu-repo/grantAgreement/ES/DGA-FSE/E47-17Rinfo:eu-repo/grantAgreement/ES/MINECO/BIO2017-84246-C2-1-Rinfo:eu-repo/grantAgreement/ES/MINECO/CTQ2017-84087-Rinfo:eu-repo/grantAgreement/ES/MINECO-FSE-FEDER/RYC-2015-18471info:eu-repo/grantAgreement/ES/MINECO/PGC2018-097583-B-I00JOURNAL OF ORGANIC CHEMISTRY 85, 14 (2020), 8944-8951All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
