Description
Summary:Chiral (S) 4-(1-methylheptyloxycarbonyl)phenyl 4′-(ω-trifluoroethoxyalcoxy)biphenyl-4-carboxylates and 4′-(ω-trifluoro-butanoyloxyalcoxybiphenyl)carboxylates were prepared and their phase transitions and the temperature dependence of the smectic layer spacings, tilt angle, spontaneous polarization, threshold and switching times for the antiferroelecrtic-ferroelectric transition were measured.
