Abstract:

Heterocycles are of great importance in thermotropic liquid crystals. Mesogens containing 1,3,4- thiadiazole have significant lateral dipole moments, wide mesomorphic temperature ranges, chemical stability and altering the molecular shape, leading to different liquid crystal behaviours. Moreover, the generation of columnar liquid crystals exhibit a molecular organization that allows the transport of energy or charge. In this abstract, we report the synthesis, characterization and mesomorphic properties of novel carboxylic acids (III a-b), amines (II a-b and IV a-b) and nitro compounds (I a-b) derived from 1,3,4-thiadiazole displaying liquid crystal properties. The synthetic route is shown in scheme 1.
