摘　　要：研究了两种非中心对称萘酞菁化合物LB膜的制备及其光谱特性,并采用二次谐波产生技术研究了它们的二阶非线性光学特性。实验结果表明,不同的取代基对萘酞菁化合物的二阶非线性影响非常大,三叔丁基氰基萘酞菁的二阶非线性极化率χ( 2 ) 为3 .7×10 - 8esu ,约为三叔丁基萘酞菁的3 7倍。Nonlinear optical properties of non-centrosymmetrical naphthalocyanine derivatives were investigated by using second harmonic generation(SHG)technique.The results shown that the substituent had a significant influence for the second order nonlinear optical properties of naphthalocyanine derivatives.The second order nonlinear optical susceptibility χ (2)of tri-tert-butyl-cyan naphthalocyanine was about 3.7×10 -8 esu,which was 37 times more than that of tri-tert-butyl naphthalocyanine.
