Their liquid crystalline properties were analyzed in relation to the molecular structure and compared with amide-containing bent-core liquid crystals from the literature. Replacement of the azobenzene structure with a unit based on stilbene, either with or without a cyano substituent, accounted for the most significant differences in liquid crystalline behavior among the synthesized compounds. Azobenzene compound exhibited an enantiotropic B7-type phase, while (cyano)stilbene compounds formed a monotropic B1Rev phase. Cyanostilbene derivatives were fluorescent and showed aggregation-induced emission (AIE) enhancement. Furthermore, these compounds showed mechanofluorochromism, as observable emission changes in the solid state as a result of mechanical grinding. These changes turned to be reversible upon fuming with tetrahydrofuran vapor. Quantum-chemical calculations were employed to provide a detailed analysis of the most probable conformers, the impact of the cyano group orientation on the transverse and longitudinal components of the molecular dipole moment, and the electronic properties. The obtained results offer valuable molecular design guidelines for the development of new stimuli-responsive self-assembled materials. info:eu-repo/grantAgreement/ES/DGA/E47-23R info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2021-122882NB-I00 info:eu-repo/grantAgreement/ES/MICIU/CEX2023-001286-S info:eu-repo/semantics/embargoedAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Ðordevic, Ivana Rybak, Paulina Pociecha, Damian Giménez, Raquel (orcid)0000-0002-7854-6316 Ros, Maria Blanca Universidad de Zaragoza (orcid)0000-0003-4416-1036 Trišovic, Nemanja 2013 765 Universidad de Zaragoza Dpto.
