Abstract

The Mixture of cholesteryl benzoate (CB) and p-Ethoxy benzolidene-butylaniline (EBBA) exhibit, cholesteric and smectic phases. The sample of 20% concentration of CB shows I-S-A-S-C*-S-E-S-B phases while cooling from isotropic phase. Optical anisotropy of cholesteric phase has been estimated using refractive index data. X-ray, thermal and optical studies have been carried out for smecticA, chiral smectic and smecticE phases. In the case of S-c* phase the `` d' spacing increases with increase of temperature. Pitch of the cholesteric phase and tilt angle of the S-c* phase have been estimated. Interesting optical textures of various concentrations have been illustrated in this investigation.
