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. info:eu-repo/grantAgreement/ES/AEI/PID2020-119512GB-I00 info:eu-repo/grantAgreement/ES/DGA/E47-20R info:eu-repo/grantAgreement/ES/DGA/E50-20D info:eu-repo/grantAgreement/ES/MCIU-FEDER/PGC2018-093761-B-C31 info:eu-repo/grantAgreement/ES/MCIU-FEDER/PGC2018-097583-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 6.0 2022 PHYSICS, ATOMIC, MOLECULAR & CHEMICAL 4 / 35 = 0.114 2022 Q1 T1 CHEMISTRY, PHYSICAL 50 / 161 = 0.311 2022 Q2 T1 0.914 2022 Atomic and Molecular Physics, and Optics 2022 Q1 Condensed Matter Physics 2022 Q1 Spectroscopy 2022 Q1 Materials Chemistry 2022 Q1 Physical and Theoretical Chemistry 2022 Q1 Electronic, Optical and Magnetic Materials 2022 Q1 9.7 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Romero, Pilar (orcid)0000-0003-1378-0571 Barberá, Joaquín Universidad de Zaragoza (orcid)0000-0001-5816-7960 Elduque, Anabel Universidad de Zaragoza (orcid)0000-0002-1373-4850 Giménez, Raquel (orcid)0000-0002-7854-6316 2010 760 Universidad de Zaragoza Dpto.
