C_(60)腈胺类衍生物的合成及三阶非线性光学性质

Synthesis and Third order Optical Nonlinearity of C_(60) Derivative

Ｃ６０的三阶非线性光学性质的研究是近年来富勒烯物理化学性质的研究热点之一［１］．研究显示，尽管Ｃ６０具有三维共轭的π电子体系，其本身并不具有大的三阶非线性系数［２,３］．但由于Ｃ６０分子具有较低的三重简并ＬＵＭＯ能级，显示出较强的电负性，能够与适当的?..

We have synthesized the C60 aminonitrile and dicyandiamide derivatives and their Fe(Ⅲ)complex. The second order hyperpolarizability γ for these derivatives have been measured by using the femtosecond optical Kerr effect at 810 nm. The relation between the value of γand the characteristic of charge transfer has been investigated.
