(orcid)0000-0002-8932-9085 Coumarin-Containing Pillar[5]arenes as Multifunctional Liquid Crystal Macrocycles 2020 Access copy available to the general public Unrestricted Liquid crystal macrocycles (LCMs) combine the unique properties of liquid crystals with those associated with macrocyclic compounds - shape persistence and the capability of hosting small molecules. 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. info:eu-repo/grantAgreement/ES/DGA-FEDER/LMP150-18 info:eu-repo/grantAgreement/ES/DGA-FSE/E47-17R info:eu-repo/grantAgreement/ES/MINECO/BIO2017-84246-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/CTQ2017-84087-R info:eu-repo/grantAgreement/ES/MINECO-FSE-FEDER/RYC-2015-18471 info:eu-repo/grantAgreement/ES/MINECO/PGC2018-097583-B-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.354 2020 CHEMISTRY, ORGANIC 12 / 57 = 0.211 2020 Q1 T1 1.2 2020 Organic Chemistry 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Romero, P.
