中文摘要： 共轭微孔聚合物类材料，由于具有刚性的骨架和可控的孔道尺寸和结构而成为共价有机框架材料中的研究重点。但是，此类材料的发展依然存在材料溶解度低、合成方法复杂、原料昂贵等问题。同时，设计合成具有光、电性能的共轭微孔聚合物材料依然是一大挑战。本项目计划针对以上问题，设计合成并研究以四嗪为骨架的新型共价有机框架材料。该类材料除具有共轭微孔聚合物的普遍优点外，四嗪简便经济的合成方法及独特的性质和反应活性将使得材料的大规模合成、光电性质研究以及框架结构的原位后修饰等得以实现。具体研究内容包括：通过实验总结归纳该类材料合成、结构和性质等相关规律，建立四嗪骨架共价有机框架研究体系；合成系列四嗪骨架共价有机框架材料，系统的开展吸附分离、光、电等性质研究；开展材料框架结构原位后修饰研究，进一步提高材料结构调控的精度并增强其功能定向合成可控性。

英文摘要： Owing to their rigid backbone and controllable pore structure,Conjugated Microporous Polymers(CMPs) have been of great interest among the covalent organic frameworks materials. However,there are several problems of this class of materials. For example, the poor solubility, complex synthesis method and expensive reagents. Also, it is really a challenge to achieve CMPs with luminescent and electrochemistry properties. To solve the problems mentioned above,we plan to design and synthesize a new kind of covalent organic frameworks materials with tetrazine as backbone. As a class of CMPs, the tetrazine based covalent organic frameworks take all the advantages of CMPs. The synthesis of materials is easy and cheap, and the luminescent and electrochemistry properties of materials are easy to realize according to the unipue properties of tetrazine. Also, it is possible to undergo in situ modification of these materials. In this project,we will try to establish a research system of tetrazine based covalent organic frameworks and find the principles of the synthesis, structures, and properties of the materials.A series of tetrazine based covalent organic framework materials shall be obtained and their properties will be systematically investigated. The in situ modification method of materials will also be studied to make
