These ionic materials have been prepared by the interaction of an amino-ended pillar[5]arene (P5N10) and three different carboxylic acids, including bent-core moieties. The bent-core units are based on ester, biphenyl, and azobenzene structures bearing two different flexible spacers between the carboxyl group and the central bent-core aromatic units. The ionic pairs segregate the molecular blocks, leading to columnar liquid crystal organizations. These ionic supramolecular compounds exhibit interesting results as proton-conductive materials. Furthermore, the introduction of azobenzene units in the bent-core structure has provided a photoresponse to the proton conduction materials. Interestingly, the amphiphilic character generated by the ionic pairs and the hydrophobic bent-core structures allows their molecular self-assembly in water solution, resulting in aggregates of appealing morphologies. The structural modifications of the bent-core units (i.e., connecting bonds at the lateral structure and spacer lengths) provide an attractive analysis on the relationship between the chemical structure and the morphology of the aggregates (fibers, chiral ribbons, nanotubes...). Additionally, the self-assembly process and evolution of the aggregates from fibers to nanotubes have been studied with several techniques. info:eu-repo/grantAgreement/ES/DGA/E47-23R info:eu-repo/grantAgreement/ES/DGA/T02-23R info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2021-122882NB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2023-150255NB-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 7.0 2024 MATERIALS SCIENCE, MULTIDISCIPLINARY 102 / 461 = 0.221 2024 Q1 T1 CHEMISTRY, PHYSICAL 45 / 185 = 0.243 2024 Q1 T1 2.065 2024 Chemical Engineering (miscellaneous) 2024 Q1 Materials Chemistry 2024 Q1 Chemistry (miscellaneous) 2024 Q1 12.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Castillo-Vallés, Martín Merino, Rosa I.
