偶氮苯聚合物(PAZOS)的合成及其三阶非线性光学特性

Synthesis and ThirdOrder Nonlinear Optical Characteristic of an Azobenzene Polymer(PAZOS)

合成及表征了一种偶氮苯聚合物聚［３′－甲基－４′－二（Ｎ，Ｎ－氧亚乙基）氨基－４－硝基偶氮苯癸二酰］（ＰＡＺＯＳ），通过简并四波混频方法（ＤＦＷＭ）研究了这种聚合物膜的三阶非线性光学性质，测得其三阶非线性光学系数χ（３）为６．６×１０－６ｅｓｕ，并考察了其相位共轭光产生特性及光致异构动力学。

Poly[3′-methyl-4′-bis(N,N-oxyethylene)amino-4-nitro azobenzene sebacoyl] was synthesized and characterized. The third-order nonlinear optical characteristic of this polymer film were studied by degenerate four-wave mixing. The χ(3) obtained is 6.6×10-6 esu. Optical phase conjugation properties and kinetics of photoinduced isomerization of the polymer film also were investigated.
