The impedance and dielectric properties of a chiral biphenylcarboxylic acid liquid crystal

Abstract

We have been synthesized a chiral rod-like liquid crystal 4'-(S)-3,7-Dimethyloctyloxy-4-biphenylcarboxylic acid (DMOBC) exhibiting enantiotropic chiral nematic (N*) as a high temperature phase as well as a smectic mesophase (SmI*) in the wide temperature range. The dielectric and impedance properties of 4'-(S)-3,7-Dimethyloctyloxy-4-biphenylcarboxylic acid (DMOBC) liquid crystal have been analyzed over the frequency range from 1 Hz to 10 MHz at the room temperature.
