Eight 2, 5-bisphenyl-1, 3, 4-thiadiazoles were synthesized. These new liquid crystalline compounds contain amide bridge linkages. Their chemical structures were established by IR and ^1H NMR spectroscopy. The liquid crystal properties were determined by POM and DSC. The results show that they all have higher phase transition temperature and wide phase transition temperature range due to introduction of the amide linkage at the thiadiazole ring.

Key words: THIADIAZOLE P, LIQUID CRYSTAL, TRICYCLIC HYDROCARBON, AMIDES, BRIDGE BOND
