摘要

4-N,N-dimethylamino 4′-N′-methylstilbazolium 4-hydroxybenzenesulfonate (DSHS) was synthesized by metathesization of N,N-dimethylamino-N′-methylstilbazolium iodide salt with sodium 4-hydroxybenzenesulfonate. The counter anion exchange reaction mechanism of the stilbazolium salt was executed. The growth of DSHS single crystal was carried out by adopting solution growth technique. X-ray diffraction studies classified the synthesized compound into the monoclinic system with P2_1/c space group. FTIR spectral analysis confirmed the existence of hydroxyl and sulfonate groups and their corresponding vibrational modes. TG-DTA measurement showed the thermal stability of the compound which is having three decomposition stages with the melting point at 312.6 °C. UV-Vis spectral analysis showed the existence of wide transmission window. PL spectral study revealed the transition mechanism of ions, where a sharp peak observed at 603 nm respectively. Laser induced damage threshold was studied for the grown crystal. Third order nonlinear optical property of DSHS crystal was studied by Z-scan test.
