GROWTH AND CHARACTERIZATION OF ORGANIC STILABAZOLIUM SINGLE CRYSTAL OF N, N- DIMETHYLAMINO-N’-METHYLSTILBAZOLIUM P CHLOROBENZENESULFONATE (DASC) IN A MIXED SOLVENT SYSTEM

Abstract

Organic nonlinear optical crystal N, N-dimethylamino-N’-methylstilbazolium p-chlorobenzenesulfonate (DASC) has been successfully grown from mixed solvent of
methanol:acetonitrile (1:1) solution by adopting slow solvent evaporation technique. Single crystal X-ray diffraction analysis was carried out and it shows that DASC crystal belongs to monoclinic structure with Cc space group. The optical absorption is studied by UV-Vis absorption spectra. Dielectric studies were also carried out for different temperature by varying the frequency.
