Growth, structural and thermal analysis of DSSS single crystals

N, N-dimethylamino-N'-methylstilbazolium 4-styrenesulphonate (DSSS), was synthesized by metathesization of the N, N-dimethylamino-N'-methylstilbazolium iodide (DASI) salt with sodium 4-styrenesulfonate. The growth of DSSS single crystal was carried out by adopting the slope nucleation coupled slow evaporation method. DSSS crystals with size 4 x 2 x 1 mm(3) were grown within a period of 15 days. The composition of the crystal was studied by CHN analysis. The melting point and thermal behavior of DSSS were investigated using differential scanning calorimetric (DSC) and thermogravimetric analyses (TGA).
