The synthesis and mesomorphic behavior of a new series of liquid crystals containing 1, 3, 4‐thiadiazole and pyridine rings with ‐CH = N‐ central group are reported. All compounds exhibit enantiotropic smectic A mesophase, but the Schiff's base analogues have no mesomorphic behavior. The influence of the pyridine ring and thiadiazole ring is discussed.
