摘要
针对水杨醛缩苯胺类席夫碱及其衍生物的非线性光学性质进行了理论研究.有限场FF/PM3方法的计算结果表明:该类化合物具有良好的非线性光学性质,尤其是三阶性质;具有内氢键的水杨醛缩苯胺二阶超极化率最大.
The dipole moments, polarizabilities, first-order hyperpolarizabilities and second-order hyperpolarizabilities of schiff base derived by the condensation of salicylaldehyde with aniline are calculated by using finite field(FF)/PM3 method. The results suggest that these compounds are good candidates for nonlinear optical materials.
