制备了 3 (1,1 二氰基噻吩 ) 1 苯 4,5 二羟基 H 噻唑 (DCNP)与聚醚醚酮 (PEK c)组成的主客掺杂聚合物薄膜 ,用Maker条纹法测量了不同掺杂浓度下薄膜的二阶非线性系数 χ3 3 (2 ) .实验结果表明 ,聚合物中生色团的含量高到一定程度 ,其宏观二阶非线性随生色团含量的增加反而下降 .本文在考虑聚合物中生色团分子相互作用的情况下 ,修正了聚合物宏观二阶非线性与生色团的含量之间的关系 ,此时聚合物宏观二阶非线性与生色团的含量已非简单的正比关系 .讨论了生色团分子间的相互作用对聚合物宏观二阶非线性的影响 ,从微观上解释了生色团分子在较高含量下其相互作用对聚合物宏观二阶非线性的衰减 The host-guest doped polymer films composed of 3 (1,1-dicyanothiophene) 1 benzene 4, 5 dihydroxythiazole (DCNP) and polyetheretherketone (PEK c) were prepared. The second-order nonlinearity coefficient of the film under the impurity concentration χ3 3 (2) .Experimental results show that the macromolecular second-order nonlinearity decreases with the increase of the chromophore content in the polymer to a certain degree. In consideration of the chromophore molecular interactions in the polymer, the relationship between the macroscopic second-order nonlinearity of the polymer and the chromophore content is corrected. In this case, the macroscopic second order nonlinearity of the polymer and the chromophore content Has been not a simple direct relationship between the chromophore molecular interactions discussed macroscopic second-order nonlinear polymer impact, microscopically explained the chromophore molecules at higher levels of its interaction on the polymer macroscopic two Non-linear attenuation
