以N-乙烯基咔唑三羰基铬为模板化合物, 选用丙烯基阳离子取代其中一个羰基配体, 合成了一种新型非平面分子内电荷转移有机金属配合物. 通过元素分析、红外、核磁共振确定了配合物的组成和结构, 电子吸收和荧光光谱结果表明配合物的光物理行为可通过配体取代调控．运用双光束前向简并四波混频(DFWM)的方法, 测试了配合物及配体的三阶非线性效应, 同时探讨了金属配位和配体取代对其的影响.

关键词: 电荷转移, 光物理, 离子配合物

Using (N-vinylcarbazole)Cr(CO)3 complex as template substrate, a novel organometallic complex with nonplanar intramolecular charge transfer property was synthesized by replacing a CO group with cationic allyl ligand. The composition and structure of the title complex were characterized by elemental analysis, IR, 1H and 13C NMR spectra. Electronic absorption and photoluminescence studies suggested that ligand exchange on the organometallic moiety offered control of the photophysical properties for this class of materials. Third-order nonlinear optical properties of the complexes and ligands in this work were measured with forward degenerate four-wave mixing (DFWM) method and discussed in relation to the metal coordination and ligand replacement.
