摘　　要：为了更深入地探讨C60衍生物的非线性光学性质,用5-(2-硫甲基-4-甲基)-嘧啶基-戊二炔-1-醇山梨酸酯与富勒烯C60进行加成反应,获得了一种新型的山梨酸酯类C60衍生物,用MALDI-TOF-MS,IR,UV-vis,1H NMR,DEPT和13CNMR进行了结构表征。利用Q倍频ns/ps Nd∶YAG激光脉冲以及z扫描技术和光限辐实验研究了该化合物的非线性折射和光限辐特性,并获得了3阶非线性光学系数和非线性吸收系数。结果表明,C60衍生物有很强的非线性吸收和非线性折射,并具有较低的光限幅箝位值,是一种非常有前途的非线性光学材料。In order to study the nonlinear optical properties of C_60 derivative,a new bridged C_60 derivative was prepared through the interaction between 5-（2-methylthio-4-methyl-5-pyrimidinyl）-2,4-pentadiyne-1-olsorbate and C_60.The molecular structure was identified and characterized by MALDI-TOF-MS,IR,UV-vis,1H NMR,DEPT and 13C NMR spectra.The optical nonlinear properties were investigated by z-scan technique and optical limiting experiment with Q-switched,double frequency ns/ps Nd∶YAG laser pulse.The experimental results show that the values of third-order optical nonlinear susceptibilities χ（3） and nonlinear absorption coefficient β.The lower value of optical limiting clamp of C_60 derivative were also found.It has a good optical limiting performance.
