Liquid crystals and supergels made out of fibers are obtained by supramolecular organization of non-discoid entities, and they notably increment the photoluminescence in these aggregated states (Aggregation-Induced Emission, AIE). The novel focal point, which is derived from 3,5-dimethyl-4-phenyl-1H-pyrazole, shows great tendency to arrange both wedge-shaped or cone-shaped dendrons in columnar arrangements by the formation of supramolecular polymers by hydrogen-bonding following the cylinder model. Two different linkers, amide or ether groups, connecting with the pyrazole-based apex are investigated, obtaining similar mesomorphic behavior, but different luminescent properties. A combined study of NMR, IR and X-ray diffraction allows establishing analogies between the fiber mesoscopic organization and the columnar organization in the liquid crystalline phase.2022http://zaguan.unizar.es/record/11974610.1016/j.molliq.2022.120109http://zaguan.unizar.es/record/119746oai:zaguan.unizar.es:119746info:eu-repo/grantAgreement/ES/AEI/PID2020-119512GB-I00info:eu-repo/grantAgreement/ES/DGA/E47-20Rinfo:eu-repo/grantAgreement/ES/DGA/E50-20Dinfo:eu-repo/grantAgreement/ES/MCIU-FEDER/PGC2018-093761-B-C31info:eu-repo/grantAgreement/ES/MCIU-FEDER/PGC2018-097583-B-I00Journal of Molecular Liquids 365 (2022), 120109 [9 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
