Abstract: In the present work, our investigation is to study on the optical and electrical properties of binary mixture of cholesteryl chloride (ChCl) and 4, 4-hexyloxy azoxy benzene (HOB). Mixtures of these molecules exhibits cholesteric, twisted grain boundary and induced smectic phases such as SmA, SmC*, SmE, and SmB phases sequentially when the specimen cooled from its isotropic phase. These phases have been characterized by using microscopic technique. Thermodynamical response of birefringence of given molecules have been discussed to understand the phase stability, chemical structure and molecular dynamics of the binary mixture of liquid crystalline materials. Temperature dependent electro-optical phase transition behaviors of the given molecules have also been discussed.
