제목 Development of New Benzothiazolium Organic Nonlinear Optical Crystals
초록 We investigate new organic nonlinear optical (NLO) materials based on benzothiazolium-based molecular cations with various benzenesulfonate counter anions having substituents at p- and m-position for CP1 and CP2 crystals, respectively. Macroscopic NLO response of CP1 and CP2 crystals is confirmed by powder second harmonic generation (SHG) test. CP1 exhibit strong SHG intensity, while CP2 doesn’t. CP1 crystals are grown by slow evaporation method for crystal structure analysis. As-grown CP1 crystals have series-type molecular assembly, similar with previously reported benzothiazolium-based analogous crystals having identical molecular cation. However, we confirmed that CP1 crystals have distinguishable intermolecular interactions between cations and anions compared to previously reported benzothiazolium-based analogous crystals. This may affect the phonon mode by suppressing molecular vibration of consisting molecules.
