Two series of novel polycatenar dyes consisting of a triazole azobenzene core were synthesized efficiently by copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction. These compounds can self-assemble into SmC and Colhex/p6mm liquid-crystalline phases, and form multistimuli responsive organogels. Bicontinuous cubic phase (CubV) could be induced in the binary system of a bicatenar compound with SmC phase and a hexacatenar compound with Colhex/p6mm phase. Photophysical investigation indicates that these compounds have reversible photoresponsive properties in solution, liquid-crystalline and gel states. They can also act as chemosensors of Fe3+ and sodium dithionite with high selectivity.

Three series of bent-shaped compounds containing the 1,2,3-triazole ring in the central core of the molecule have been prepared by the most extended "click chemistry" reaction, the copper-catalyzed azide-alkyne cycloaddition (CuAAC). This research demonstrates the versatility of this synthetic approach with the aim of achieving innovative compact supramolecular organizations. The appropriate combination of the 1,2,3-triazole synthon linked either to a methylene unit (series M) or to a methylenoxycarbonyl block (series MC) has allowed the induction of a variety of non-classical bent-core liquid crystal phases versus the classic mesophases promoted by 1,4-diphenyl-1,2,3- triazole derivatives (series T). Through a suitable selection of common lateral structures connected by "click chemistry" both the transition temperatures and mesomorphism, ranging from lamellar to columnar or B4-like supramolecular liquid crystalline organizations, can be tuned.
