Abstract

Compounds 1a–j, 4-alkoxy-4′-pentafluorobenzoyloxybiphenyls, were synthesized to investigate the biaxiality in the smectic A phases of rod-like molecules possessing both perfluorinated and non-fluorinated benzene rings. The phase behaviors of the compounds and the molecular packing structures of their smectic A phases were investigated by polarized optical microscopy (POM), differential scanning colorimetry (DSC), and X-ray ...
