摘要

3-Alkyl-2,5-bis[p-(hexa-2,4-dienoyloxy)phenyl]-thiophene derivatives were synthesized by using Kumada coupling and Suzuki coupling reactions as key steps. The thermotropic liquid crystalline behavior of these compounds was investigated by optical polarized microscopy, monotropic nematic mesophases were observed in such compounds.
