摘要
本文采用电场诱导二次谐波(EFISH)方法对所合成的10个金属有机分子的二阶非线性极化率进行了测试.这10个化合物是具有电子给体-受体共轭结构的二茂铁衍生物,它们的非线性极化率大多未见报道.本文系统地研究了分子的给体-受体强度、共轭长度、共轭体系及共平面性等结构因素与分子二阶非线性极化率的关系.
Second - order molecular polarizabilities of ten ferrocenyl derivatives which possess donor - acceptor conjugated structures have been determined with DC electric - field - induced second- harmonic generation (EFISH) experiments. The relations between the molecular structure and nonlinear optical property are discussed. Issues concerning donor - acceptor strength, conjugation length, linkage and planarity are included.
