中文摘要：
二阶非线性光学高分子材料是实现以光子为信息载体之一的光电子技术所必需的一类重要材料，在远程通讯、数据存储、相位共轭等方面具有巨大的应用前景。而如何有效地将小分子高的β值转化为高分子材料大的宏观二阶非线性光学性能是目前二阶非线性光学高分子材料性能优化的一个难题。本课题拟以具优异性能的无机高分子――聚磷腈作为母体，将树枝状结构的发色团以侧基的形式引入高分子体系，制备新型的聚磷腈二阶非线性光学材料，研究其构性关系，探讨其应用前景。树枝状发色团颇具优势的构型和强偶极作用可被削弱的特点，以及聚磷腈主链优秀的光学透明性（200nm——近红外没有吸收），良好的光、热稳定性和合成的易裁剪性，将赋予这类新型聚磷腈二阶非线性光学材料很好的综合性能，极有希望满足实际应用的要求。我们合成了多个系列的二阶非线性光学高分子，并基于实验事实，首次提出对于一个给定的发色团，给定的连接位置，必然有一个合适的间隔基团，可以有效地将小分子发色团的微观二阶非线性光学性能更好地转化为材料大的宏观二阶非线性光学效应。这就是“合适间隔基团概念”，可以为解决上述难题提供有益的参考。
