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 structure and composition of the crystal were studied by single crystal X-ray diffraction, CHN and nuclear magnetic resonance (NMR) analyses. The FUR results reveal the existence of the vinyl groups and their corresponding vibrational modes. The melting point and thermal behavior of DSSS were investigated using differential scanning calorimetric (DSC) and thermogravimetric analyses (TGA). (C) 2011 Elsevier B.V. All rights reserved.
