通过低热固相反应,我们合成了蝶型簇合物[MoOS_3Cu_2(PPh_3)_2(Py)_2](1),该簇合物与PPh_3反应,可以得到另一个新的簇合物[MoOS_3Cu_2(PPh_3)_3(Py)](2).使用Z-扫描方法测试这两个化合物的三阶非线性光学性质,发现它们都有较强的非线性光学吸收性质,非线性光学吸收系数分别是1.5×10~(-11)mW~(-1)和3.3×10~(-10)mW~(-1).
Through the low-temperature solid-state reaction, we have synthesized the butterfly cluster [MoOS_3Cu_2 (PPh_3) _2 (Py) _2] (1), which can react with PPh_3 to obtain another new cluster [MoOS_3Cu_2 (PPh_3 ) _3 (Py)] (2) .Third-order nonlinear optical properties of these two compounds were tested by Z-scan method and found to have strong nonlinear optical absorption properties. The nonlinear optical absorption coefficients were 1.5 × 10 ~ (-11) mW ~ (-1) and 3.3 × 10 ~ (-10) mW ~ (-1).
