Three salts built up from (E)-4′-(dimethylamino)-stilbazolium (DMAS)H+, (E)-4′-(diethylamino)-stilbazolium (DEAS)H +, (E)-4′-{2-(methoxymethyl) pyrrolidinyl}-stilbazolium (MPS)H+, and gold cyanide as a counter-ion, are rep

DAST (1-methyl-4-{2-[4-(dimethylamino)phenyl]ethenyl}pyridinium p-toluenesulfonate) is a promising crystalline material for electro-optic applications and THz-wave generation. DAST powder for crystal growth was prepared by two synthesis routes including the conventional one and we confirmed that purity of DAST powder became indistinguishable after proper recrystallization even using conventional synthesis process. The highest solubility of DAST was found for methanol-acetonitrile mixture, and DAST crystal growth in this mixture or methanol-ethanol mixture gave thicker crystals than those grown in methanol. Thus, morphological control of DAST single crystals was found to be possible by varying solvents.

The excited-state reaction of push-pull styryl system was studied in this work. In the excited state, compounds of 2-StP-NMe2, 2-StQ-NMe 2, 4-StQ-NMe2 and 4-StP-NMe2 possess a sufficiently large acidity change f
