Physical Properties of Some Chiral Smectic Liquid Crystals Having 1-Methyl-Alkoxy-Phenyl Group

Abstract
The liquid crystalline compounds having an optically active 1-methyl-alkoxy-phenyl group were synthesized. They show some abnormality, i.e., firstly rather high value of spontaneous polarization for the structural feature lacking a strongly polar group, in the vicinity of the chiral center, and secondly the sense of twist in the S*c phase that is opposite to what was originally expected. We report the characteristics of these compounds.
