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 condChemistry of materials : a publication of the American Chemical Society9793-9805https://www.ebi.ac.uk/biostudies/studies/S-EPMC11468781biostudies-literatureIonic Bent-Core Pillar[&lt;i&gt;n&lt;/i&gt;]arenes: From Liquid Crystals to Nanoaggregates and Functional Applications.PMC11468781Serrano JLMarin IRos MBBarbera JMerino RIFolcia CLCastillo-Valles MfalseIonic Bent-Core Pillar[&lt;i&gt;n&lt;/i&gt;]arenes: From Liquid Crystals to Nanoaggregates and Functional Applications.Herein, we report the first examples of supramolecular systems from bent-core-based pillar[<i>n</i>]arenes through ionic bonds.
