基于点击化学方法合成线形聚三唑高分子
摘要：近年来，点击化学（click chemistry）以其高产率、高选择性以及对各种官能团优异的耐受性成为化学家和材料科学家们手中有力的研究工具。目前研究最多、最成熟的点击化学是Cu(Ⅰ)催化的炔-叠氮基团的1,3-偶极环加成反应。第一章综述了点击化学的进展，对Cu(Ⅰ)催化的叠氮化合物与端炔化合物之间的1,3-偶极环加成反应进行了理论分析，并介绍三唑衍生物的应用。在第二章内容中，我们分别以咔唑和偶氮苯为原料合成3,6-双炔咔唑单体和末端双炔偶氮苯单体，将其分别与双叠氮化合物反应，合成含主链含咔唑或偶氮苯功能团的线形聚三唑高分子化合物。最后，对本课题做了总结和展望。

Abstract：In recent years, due to high yield, high selectivity, as well as excellent tolerance to a variety of functional groups, click chemistry has been becoming a powerful research tool for chemist and material scientists. Cu (Ⅰ)-catalyzed alkyne-azide 1,3-dipolar cycloaddition reaction is one reaction which is the most used and the most mature in click chemistry. In the first chapter, we review the progress of click chemistry, and give the theoretical analysis of Cu (Ⅰ)-catalyzed 1,3-dipolar cycloaddition reaction between azide and terminal alkyne compounds, furthermore, we describe the application of triazole derivatives. In the second chapter, we use carbazole and azobenzene as raw materials to synthesize 3,6-ethynyl-carbazole and diacetylene azobenzene monomers, respectively, which futher react with diazide to synthesize linear polytriazole polymer containing carbazole or azobenzene backbone. Finally, we give a summary and outlook for this project.
