Induced Chiral Smectic Phase in Mixtures of Mesogenic and Non-Mesogenic Compounds
The mixture of cholesteryl chloride (CCl), cetyl pyridinium chloride, and ethylene glycol exhibits very interesting liquid crystalline mesophase cholesteric (N*) and induced smectic phases, such as Sm A, Sm C*, and Sm E, sequentially when the specimen is cooled from its isotropic liquid phase. These phases have been characterized by using differential scanning calorimetric (DSC), X-ray diffraction, nuclear magnetic resonance (NMR), infrared (IR), and optical texture studies.
