The growth of an efficient organic nonlinear optical material 4-N, N-dimethylamino-N′-methylstilbazolium p-chlorobenzenesulfonate (DASC), a derivative of the stilbazolium tosylate family has been reported by employing the slope nucleation method coupled with slow solvent evaporation. The crystal system and lattice parameters are estimated by single crystal X-ray diffraction. The second harmonic conversion efficiency of DASC was determined using the Kurtz and Perry powder technique. The thermal stability of the compound is determined by thermo gravimetric/differential thermo gravimetric (TG/DTG) and differential scanning calorimetric (DSC) techniques. The hardness profile of the sample is investigated by Vickers microhardness test. The dielectric constant and dielectric loss of the crystal were studied as function of frequency. The surface properties of DASC are reported by undertaking scanning electron microscopy (SEM) and atomic force microscopy (AFM) studies.
