Electro-Optical Phase Transition Studies ofChiral SmecticPhase of Nematic and CholestericMaterials

Abstract

In the present work, our investigation is to study the electro-optical properties of the binary mixture of cholesteric and nematic compounds, namely, cholesteryl chloride (ChCl) and n-(4-n-butoxy benzylidene-4-n octylaniline (4O.8), which exhibits a very interesting liquid crystalline cholesteric and induced chiral smectic phases like SmA, SmC∗, SmC, and SmB phases sequentially when the specimen cooled from isotropic phase. Transmittance and electro-optical phase transition studies have also been discussed.
