Abstract

In order to enhance the second-order nonlinear optical coefficient d of 1-methyl-4-(2-(4-(dimethylamino)phenyl)ethenyl)pyridinium p-toluenesulfonate (DAST), polyene analogues of DAST cation having increased double-bond number between pyridinium and (dimethylamino)phenyl rings were prepared. As counter anions, iodide, p-toluenesulfonate and 4′-(dimethylamino)azobenzene-4-sulfonate were introduced. For benzenesulfonate salts, pure and water containing crystals were obtained. X-ray crystallographic analysis could be performed for two water containing crystals. One of two crystals were found to belong to triclinic space group P1, and its d value was estimated to be about 1.3 times of that of DAST.
