摘要

A novel series of asymmetricallyend-capped mesogenic oligothiophenes,with various oligothiophenecore lengths, alkoxy tail lengths, and molecular polarities through introducingalkylsulfanyl or alkylsulfonyl functionalitiesas the terminal group, havebeen synthesized by palladium-catalyzedSuzuki cross-coupling and Kumada cross-coupling reactions askey steps. For the single end-cappedoligothiophenes, CmO-Ar-OT(4)-H inwhich m=10, 12, 14, 16, and 18, all of these oligomers exhibited a broad temperaturerange of highly ordered smectic E and enantiotropic nematic phases,apart from the one with the longest octadecyloxytail.
