采用四波混频方法测量了Ru络合物在450 nm处的三阶极化率和三阶超极化系数,并对不同配体和取代基对三阶超极化系数的影响进行了定量和定性的分析。发现在该类型结构中,取代基的负电性对C值的影响很大。

The nonlinear optical properties of Ru complexes and coordination compounds were studied by degenerate four wave mixing (DFWM) measurements at 450 nm. The third order nonlinear optical susceptibility and the third order hyperpolarizability were measured. The third order hyperpolarizabilities of coordination compounds and substitution groups were qualitatively and quantitively discussed. It is found that substitution groups signifiantly enhanced the γ value.
