Opto-electrical and thermodynamic characterization of liquid crystallinematerials

T.N.Govindaiah

We report the results of our studies on optical and thermal properties of binary mixture of compounds, viz., p-butoxybenzylidene, p-heptylaniline (BBHA) and cholesteryl nanonate (CN). The mixture exhibits a very interesting twisted grain boundary (TGB) and re-entrant smectic-C (ReSmC) for different concentrations of BBHA sequentially when the specimen is cooled from its isotropic phase. The temperature variations of opticaldensity and electrical conductivity have been discussed. Thermodynamic studies have also been discussed to understand the phase stability, chemical structure and molecular dynamics of the binary mixture of liquid crystallinematerials.
