| 摘 要： | 首次合成了一种称之为聚苯乙烯芪盐的有机高分子材料.此材料可以在水面上形成稳定的单分子层膜,并且所形成的单分子层膜可以转移到固体衬底上去.对聚苯乙烯芪盐单分子层膜进行光学二次谐波产生测量,得到聚苯乙烯芪盐对应于每个发色团的二阶非线性极化率为1.2×10~(-28)esu.制备了该材料两种不同类型的多层膜,讨论了多层膜二次谐波产生信号不随层数增加而增加的可能原因.

| Abstract: | A stilbazium salt polystyrene was synthesized as a pre-polymerized organic material for Langmuir-Blodgett (L-B) film fabrication and nonlinear optical property study. This material can form stable monolayer on a water surface to be transferred onto solid substrates. Second harmonic generation (SHG) studies on monolayer showed that the second order polarizability per chromophoric group of this material was 1. 2× 10-28esu. Multilayers of two different types of this material have also been fabricated and studied by SHG measurement. The results are discussed. |
