Two or more multicomponents system of cholesteryl ethyl corbonate, didodecyl dimethyl ammonium bromide, and ethylene glycol exhibits liquid crystalline phase of cholesteric and induced smectic phases, such as SmA, SmC, SmC*, and SmE, sequentially when the specimen is cooled from isotropic liquid phase. These phases have been characterized by using X-ray and optical texture studies. The temperature variation of optical anisotropy and electrical conductivity has also been discussed.
