高分子合成是高分子学科的基础，合理选择有机反应制备新型聚合物是高分子合成方法学的重要研究内容。本着“从新角度看待旧反应”的原则，本课题组发现多组分反应与点击反应存在交集，由此提出了多组分点击化学的概念，并筛选了可视为点击反应的高效多组分反应。在前期研究中，我们初步尝试了在高分子合成领域应用多组分点击反应，合成了新型高分子。在本项目中，我们将进一步以高分子合成方法研究为导向，在高分子合成领域系统、充分地应用多组分点击反应，发挥其优势与特点（起始物安全易得、高效偶联、易于引入新功能），制备具有特殊结构与功能的新型聚合物；并利用多组分点击反应耐受性好的特点，将其与可控自由基聚合相结合，发展多组分一锅法聚合体系。通过执行本项目，我们希望建立特色鲜明的、以多组分点击化学为基础的高分子合成体系，并为后继的拓展工作，如深入研究聚合物独特的物理化学性质、功能，探索其应用前景，打下坚实的实验基础。

Polymer synthesis is the starting point of polymer science, screening and using suitable organic reactions to prepare novel polymers is the core of polymer synthesis. Based on the principle ‘looking at old reactions from new perspectives’, the common features between multicomponent reactions (MCR) and click reactions have been realized, leading to the multicomponent click chemistry, i.e. some highly efficient MCRs can be recognized as click reactions. Therefore, some multicomponent click reaction have been screened and utilized to prepare novel functional polymers. In current project, we will systematically use multicomponent click reactions (easy available and safe reactants, high efficient coupling reaction, easy introducing new functions) in polymer chemistry to prepare series of new polymers with unique structure, property and function. Meanwhile, we will also combine multicomponent click reactions with controlled radical polymerization to construct one-pot polymerization systems to facilely synthesize new functional polymers. Through current project, we will develop distinctive polymer preparation systems based on the multicomponent click reactions, and lay a solid experimental foundation for the future detailed study of those special polymers.
