摘要：

Two homologous series: (S) 4-(1-methylheptyloxy-carbonyl)phenyl 4'-(3-alkanoyloxyprop-1-oxy)biphenyl-4-carboxylates and 4'-(3-perfluoroalkanoyloxyprop-1-oxy)biphenyl-4-carboxylaces were synthesized and their smectic phases and phase transitions were investigated using polarizing microscopy, DSC calorimetry and miscibility methods. Mixtures with a broad temperature range of the antiferroelectic smectic C-A* phase and phase sequence C-A*-A-I or C-A*-CI-A-I were formulated.
