The novel compounds are fluorescent both in solution and in condensed phases, achieving brighter fluorescence in the last case with fluorescence quantum yields up to 60%. Depending on the number of pyrene units (1 or 2) and/or the presence or absence of a long and flexible linker between the bent-core and the pyrene structures, bent-core liquid crystal phases, physical gels and nanoassemblies were obtained. Their properties depend on the molecular design, unveiling a synergistic and versatile ''tandem'' of the bi-functional system in supramolecular functional materials chemistry. Long hydrocarbon spacers connecting bent-core and pyrene structures were necessary to display mesomorphic properties, achieving monotropic rectangular columnar mesophases, being for one compound stable at room temperature and displaying a glassy transition below room temperature, as revealed by POM, DSC and XRD. Liquid crystal phases exhibited excimer-like emission. In addition, organogels were obtained without the help of hydrogen bonding functionalities, exhibiting in one case supergelator behavior. Different nanoassemblies were obtained from these non-amphiphilic bent-core structures, in particular unprecedented organic nanotubes with beveled ends formed by a single bilayer. © 2022 The Royal Society of Chemistry. info:eu-repo/grantAgreement/ES/DGA/E47-20R info:eu-repo/grantAgreement/ES/MCIU-FEDER/PGC2018-093761-B-C31 info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2015-66208-C3-1 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 6.4 2022 PHYSICS, APPLIED 32 / 160 = 0.2 2022 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 86 / 343 = 0.251 2022 Q2 T1 1.534 2022 Materials Chemistry 2022 Q1 Chemistry (miscellaneous) 2022 Q1 11.8 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Varghese, Shinto Gierschner, Johannes Giménez, Raquel (orcid)0000-0002-7854-6316 Ros, M.
