金属有机非线性光学材料

Review of Organometal Nonlinear Optical Materials

本文介绍了非线性光学的简史、非线性光学材料的分类及应用，简述了金属有机非线性光学材料的原理，从分子工程和晶体工程的角度讨论了金属有机非线性光学材料的结构与性质的关系．综述了目前已研究的金属有机化合物和金属有机聚合物的二阶、三阶非线性光学材料，二阶非线性光学材料按目前所做的工作可以分成二大类：一类是含有芳香基或杂环的过渡金属羰基化合物；一类是含有二茂铁基和吸电子基的共轭体系化合物。三阶非线性光学材料的研究工作主要集中在酞菁类的金属配合物上。本文对金属有机化合物作为非线性光学材料的独特之处进行了总结，并对金属有机非线性光学材料的前景作了展望。

In this paper,the history of noulinearoptics,the classification of nonlinear opticalmaterials and the application of nonlinear opticalmaterials were introduced and the theory oforganometal nonlinear optical materials wasdescribed simply. The relations between structuresand properties of organometal noulinear opticalmaterials were discussed from angles of molecular engineering and crystal engineering.The second-order and third-order noulinear optical materials of organometal compound and polymer stuided up date were reviewed.The second-order noulinear optical materials can be divided into two kinds according to the papers done now.One is the transition-metal carbonyl colnpounds containing aryl or heterocycle.Tbe other is conjugated system compounds containing ferrocenyl and electron-withdrawingsubstituent.The research of third-order nonlinearoptical materials mainly facus the phthalocyanine-metal complexes.In this paper,special advantage oforganometal compound and polymer as nonlinearoptical material was summarized and the prospect oforganometal noulinear optical materials was lookedforward.
