[1,2,3]-triazole derivatives: Mesomorphic property dependence on the molecular shape
Résumé
Nowadays, heterocyclic units have been extensively studied for the preparation of thermotropic liquid crystals due to their ability to impart
lateral and/or longitudinal dipoles and induce changes in molecular shape. Key parameters to accede to stable mesophases are the position
of the heterocycle and the nature of terminal and linking functions. We present in this paper, an overview of several series of 1,2,3-triazole liquid
crystalline derivatives thatwe designed and characterized.We highlight the effect of different connecting functions and the geometry of mesogenic
core on the mesomorphic behavior of these derivatives.
