A new type of five-membered heterocyclic 1,2,4-triazoles (1-5) with various substituents on the N-4 position, such as benzyl, phenyl or n-alkyl groups, utilized as core group to generate room temperature columnar mesophases is reported. The presence of lone pair electrons on the nitrogen atoms and/or nonplanarity in this type of heterocyclic structure might be responsible for the formation of the columnar mesophases and the resulting lower melting and clearing temperatures.

A series of substituted 2, 5-diaryl-1, 3, 4-thiadiazole derivatives are prepared by microwave-assisted synthesis in the absence of an organic solvent. All derivatives are well characterized by 1H and 13C NMR, MS, and elemental analys
