摘要：

The binary mixture of two nonmesogenic compounds viz., DTAC and EG exhibits very interestingly induced polymorphism of smectic phase's at large range of concentrations with temperature. The mixture with range of concentrations below 50% of DTAC exhibits SmA, SmC, SmC* SmE, and SmB phases, sequentially when the specimen is cooled from its isotropic phase. Different liquid crystalline phases observed in the mixture were studied using DSC, X-ray, and Optical microscopic techniques. The temperature variations of optical anisotropy and electrical conductivity have also been discussed.
