摘　　要：参照文献制备了铜 (Ⅱ )的二茂铁 β -二酮配合物 ,CuL2 (L =C5H5FeC5H4COCHCOCH3 )。采用元素分析、红外等方法对其进行了结构表征 ,采用Z -scan法在DMF溶液中测试了该化合物的三阶非线性光学性能 ,发现它有很强的非线性吸收 (α2 =2 .4 3× 10 -9mW-1)和强的非线性折射 (n2 =2 .0 2× 10 -17m2 W-1) ,三阶非线性系数 χ(3 ) 和分子超极化率γ分别为 4 .93× 10 -11esu和 1.6 4× 10 -2 8esu .According to literatures referred, a ferrocenyl β-diketonenato Cu(Ⅱ) compound CuL_2(L=C_5H_5FeC_5H_4COCHCOCH_3) is prepared. Its structure is characterized by elemental analysis and IR. Moreover, its third-order nonlinear optical (NLO) properties are determined by Z-scan technique in DMF solution. The results indicate that, the complex exhibits very strong NLO absorption and strong self-focusing effect. The third-order NLO absorption coefficient α_2 is 2.43×10^(-9)mW^(-1), refractive index n_2 is 2.02×10^(-17)m^2W^(-1);effective susceptibility χ^((3)) and hyperpolarizability γ value are 4.93×10^(-11)esu and 1.64×10^(-28) esu respectively.
