제목 New Organic Nonlinear Optical Crystals based on N-Benzyl Pyridinium Core Structure with High Environmental Stability
초록 We investigate new cation core structures based on N-benzyl pyridinium salt with various substituents ( X : -H ; BP1, -CH3 ; BP2, -(CH3)2 ; BP3 ) on the benzyl group for noncentrosymmetric molecular ordering in the crystalline state. In BP3 chromophore, two methyl groups on the benzyl ring can be gave more asymmetry of the chromophore shape. Among three N-benzyl pyridimium cations with p-toluenesulfonate anion, BP3 crystals exhibit acentric crystal structure (monoclinic P21 phase) with a large macroscopic optical nonlinearity. The BP3 crystals have not formed hydrated phase with water in contrast to DAST crystals. Moreover, the one-order lower solubility in water of BP3 than DAST causes good humidity resistance and can apply various crystal growth techniques.
