제목 Development of New Electro-Optic Ionic Crystals by Cationic Engineering with Halogen Substituents
초록 We report on new electro-optic organic ionic crystals based on quinolinium electron acceptor-based cations having halogen substituents with aromatic anions. F1 crystals introducing with fluorine substituent on cation show identical crystal structure with non-halogenated analogous crystals. On the other hand, F1 crystals exhibit different THz spectral shape from non-halogenated analogous crystals, which resulted from newly created hydrogen bonds by fluorine substituents. Meanwhile, C1 and C2 analogous crystals introducing with other halogen substituents on cations show different crystal structure and increased π-π stacking distance compared to non-halogenated crystals. This change results in enhancement of macroscopic optical nonlinearity.
