Fluorocarbon and hydrocarbon end groups: effects on mesomorphism and physical properties of smectic liquid crystals

Author affiliations

Abstract

In this article we examine the effects of cyclohexane and perfluorocyclohexane being used as bulky end groups on the mesomorphism of classical smectic liquid crystal mesogens. The mesogen that is used in this work is typical of the MHPOBC family of materials. The mesophase behaviour is investigated and miscibility studies are carried out. Electro-optical evaluation of the materials is investigated to show the effect of the terminal group on physical properties such as spontaneous polarisation and tilt angle.
