Abstract
Mesomorphic properties (phase transitions enthalpies and temperatures) and the dependence of smectic layer spacings upon reduced temperature for eight homologous series of three ring ester such as: (S)-(+)-4-(1-methylheptyloxycarbonyl)phenyl or (S)-(+)-4-(1-methylheptyloxycarbonyl)-3-fluorophenyl or (S)-(+)-4-(1-methyl-heptyloxycarbonyl)-2-fluorophenyl 4'-(perfluoroalkanoyloxyhexyloxy)biphenylates and 4'-(alkanoyloxyhexyloxy)-biphenylates, and (S)-(+)-4-(1-methylheptyloxycarbonyl)biphenyl-4-yl 4'-(perfluoroalkanoyloxyhexyloxy)benzoates and 4'-(alkanoyloxyhexyloxy)benzoates were described. The terminal chain fluorinated compounds have SmC*anti-SmC*-SmA-Iso phase sequence and a high tilted (orthoconic) antiferroelectric phase in broad temperature range.
