We design and synthesize a new nonlinear optical organic salt crystal X1 based on phenolic benzothiazolium cation with counter anion having substituents with strongly electronegative groups. Using powder second harmonic generation measurement, we observe a strong second harmonic generation signal. It is confirmed that X1 crystals have acentric crystal structure. X1 crystals are grown by solution growth method in methanol for X-ray single-crystal structure analysis. Compared previously reported 4-methyl benzenesulfonate and 2,4,6-trimethylbenzenesulfonate anions, X1 shows different crystal structures. In addition, we investigate the crystal characteristics and physical properties of X1 crystals by using various instrumental techniques including thermogravimetric analysis (TGA), difeerential scanning calorimetry (DSC) and X-ray crystallography. |
