Synthesis and Properties of Ferroelectric Liquid Crystals Having a Biphenyldioxanyl Core

Abstract

Ferroelectric liquid crystals (FLCs) having a short response time have been investigated with respect to their application for high resolution graphic display. It is found that introduction of fluoro substituents to the molecule in a suitable position such as in a core and in an asymmetric tail allowed the compounds to have a short response time. Here, in order to obtain further information about a fluorination effect on the structure, a new series of ferroelectric liquid crystals having a biphenyldioxanyl core has been synthesized. Their mesomorphic and physical properties have been measured, and the correlation between the structures and the properties will be reported.
