| 摘 要： | 研究了三种萘酞菁化合物LB膜的制备,并通过二次谐波产生的方法研究了单个对称取代的萘酞菁化合物及双(四叔丁基萘酞菁)铒的二阶非线性光学特性,并对它们的产生机理进行了简单的讨论.单个对称取代的萘酞菁化合物,它们的二次谐波产生机制为磁偶极子耦合机制,双(四叔丁基萘酞菁)铒的二阶非线性光学特性起源于电四极子模型,且它的二阶非线性极化率χ(2)(或超极化率β)大于单个萘酞菁化合物. |

| Abstract: | Deposition of Langmuir-Blodgett and second order nonlinear optical properties of three centrosymmetric naphthalocyanine derivatives were investigated by using second harmonic generation (SHG) technique. The mechanisms of nonlinearity were discussed simply. For symmetrical single naphthalocyanine molecule, the origin of SHG was the magnetic dipole coupling mechanism. The bi-(tetr-tert-butyl-naphthalocyaninato)-orbium molecule is also a centrosymmetric molecule, the origin of SHG was the electric quadrupole mechanism. The second order nonlinear optical susceptibility χ(2) of bi-(tetr-tert-butyl-naphthalocyaninato)-orbium was bigger than that of tetr-tert-butyl- naphthalocyanines. |
