The growth an ionic organic nonlinear optical crystal of 4-N, N-dimethylamino-4-N-methyl-stilbazolium p-methoxybenzenesulfonate (DSMOS), one of the efficient derivatives of stilbazolium has been reported. The growth experiment is performed by a relatively simple and cost effective approach adopting the slope nucleation method coupled with slow evaporation (SNM-SE). The grown crystal has been subjected to single crystal X-ray diffraction study. The actual composition and various functional groups present in the sample are identified from nuclear magnetic resonance (NMR) and Fourier transform infrared (FT-IR) spectral studies. The thermal properties are investigated by thermogravimetric and differential scanning calorimetric (TG/DTG and DSC) techniques. The nonlinear optical, mechanical and surface properties are also reported.
Graphical abstractThe solution was prepared in a Teflon beaker with a Teflon plate with parallel grooves which was sealed with a perforated cap and kept in a constant temperature bath at 35 °C. After 3–4 weeks of evaporation, crystals with size up to 8 × 3 × 3 mm3 were harvested. The DSMOS crystals appeared red in colour are shown in the photograph.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► A highly efficient organic NLO crystal of DSMOS was grown by cost effective approach. ► Growth conditions were optimized. ► The investigated physicochemical properties reveal the moderate quality of the crystal.
