Structural Properties of the Ferroelectric Liquid Crystal Mixtures Based on the Homologous Series of Alkoxyphenyl Alkoxy Benzoates

Abstract

The temperature dependence of the layer spacings and the average intermolecular distances were studied in smectic A, C, B and nematic phases by X-ray diffraction on non-oriented samples. Two representatives of 4-n-alkoxyphenyl 4′-n-alkoxy benzoates, furthermore their eutectic binary mixture, and ternary ferroelectric mixtures obtained by the chiral additive of (R)-(1-methylheptyl)-1, 1′-4′-1′-terphyenyl-1, 4′-dicarboxilate used in different concentrations were investigated by small and large angle measurements as well.
