合成了两种类型共九个新的金属有机电荷转移盐(CpFeBz)n[M(mnt)2]和(CpFeBz)n[M.(dmit)2](M=Ni, Pd, Pt,Cu, Co; Cp代表环戊二烯基; Bz代表苯; 通过元素分析、IR和1H NMR对化合物进行了鉴定。用简并四波混频的方法首次研究了金属有机电荷转移盐的三阶非线性光学性质。结果表明, 这类金属有机电荷转移有较大的近共振三阶非线性光学响应。

Two series of new organometallic salts (CpFeBz)nM(mnt)2 and (CpFeBz)nM(dmit)2 (M=Ni, Pd, Pt, Cu or Co; Cp=Cyclopentadienyl, Bz=Benzene, H2mnt=maleonitriledithiol; H2dmit=4, 5-dimercapto-1, 3-dithiole-2-thione, n=1 or 2) were synthesized by metathetical reaction. They were characterized by EA, IR and 1H NMR. The third-order optical nonlinearity of organometallic salts was studied by DFWM method for the first time. These molecules exhibit second hyperpolarizability which is in the order of 10^-^3^0 esu. The results also show that the nonlinearity mainly comes from the contribution of the planar conjugated anions.
