由于在分离膜、特种工程塑料、生物医用高分子、有机光电材料等领域都具有潜在的应用前景，含1,2,3-三氮唑结构的高分子近期得到了广泛关注。本项目拟从单体设计角度出发，通过改进型Wolff环缩合反应，采用α-重氮乙酰乙酰芳胺和各种伯胺作为原料，通过三种途径分别制备含1,2,3-三氮唑的功能高分子，并进一步研究此类含多取代1,2,3-三氮唑结构的高分子的功能特性。此方法不仅具备了传统Wolff制备1,2,3-三氮唑的高区域选择性、原料丰富易得及多取代基团等优点，并且还具备了常用的通过有机叠氮与炔的“点击化”反应制备1,2,3-三氮唑的高产率、反应操作简单等优点。本项目的顺利实施将为含1,2,3-三氮唑结构的聚合物在功能高分子中的推广应用奠定了科学基础。

Recently, polymers containing 1,2,3-triazole moieties have been receiving increasing attends due to their potential applications in the field of separation membranes, engineering plastics, biomedical devices, and organic optoelectronic materials. In this proposal, we purpose to synthesize a variety of 1,2,3-triazole-containing polymers through three pathways based on modified Wolff’s cyclocondensation reactions, using α-diazo-β-oxoamides and primary amines as the staring materials. Then the properties of these multi-substituted 1,2,3-triazole-containing polymers will be systematically characterized. The approaches to 1,2,3-triazole-containing polymers in this proposal enjoy not only the advantages of traditional Wolff’s 1,2,3-triazole synthesis such as high regioselectivity, abundant raw materials, and the possibility multi substitutions, but also the virtues of frequently-used click chemistry based on organic azides and terminal alkynes including high yields and feasibility. The accomplishment of this project will lay scientific foundation for the applications of 1,2,3-triazole-containing polymers as functional materials.
