摘要：制备和研究了三氮杂桥C60衍生物(C60TA)的非线性光学性质。利用紫外(UV-Vis)、质谱(MS)和核磁(NMR)对制备的C60TA进行结构表征,UV-Vis谱图450 nm波长处无明显线性吸收,是非常好的非线性光学化合物。利用Z-扫描实验测定了在波长为532 nm、脉宽为8 ns条件下C60TA的非线性性能,结果发现,其具有很强的非线性吸收和非线性折射,通过计算得到三阶非线性光学系数χ(3)=7.11×10-12esu、非线性吸收系数β=2.17×10-10m/W和非线性折射率n2=2.58×10-11esu。研究了C60TA和C60的光限辐性能,比较发现,C60TA的光限辐性能明显优于C60。以上结果表明,C60TA是一种具有非线性光学特性的化合物。
The nonlinear optical properties of triaza-bridged fullerene derivative are reported.First,the structure was characterized by UV-vis,MS and NMR spectra.The compound has good nonlinear optical properties in UV-vis spectrum at 450 nm.Then the optical nonlinear property of this compound were measured using a Q-switched Nd：YAG laser with 8 ns pulse width at 532 nm.The reverse saturation absorption and nonlinear refraction were observed by means of Z-scan technique.The values of third-order optical nonlinear susceptibilities χ（3）,nonlinear absorption coefficient β and nonlinear refractive index n2 were obtained,respectively.The optical limiting properties of this triaza-bridged fullerene derivate and fullerene were also studied and the results show that it has better optical limiting than the fullerene.These results show that the triaza-bridged fullerene derivate is a better nonlinear optical compound.
