Liquid Crystals based on carboxylic acids, amines and nitro compounds derived from 1,3,4-thiadiazole.

Heterocycles are of great importance in thermotropic liquid crystals. 1 Mesogens containing 1,3,4thiadiazole have significant lateral dipole moments, wide mesomorphic temperature ranges, chemical stability and altering the molecular shape, leading to different liquid crystal behaviours. 2 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.
