氨基功能化聚合物的合成
The synthesis of amine functionalized polymers
摘 要
金属有机配位聚合物又称金属有机框架材料(Metal Organic Frameworks，MOFs)是一种多孔的晶体材料，由于其具有高的比表面积、规则的孔道结构和可功能化等特点而倍受关注，MOFS在气体吸附、分离及催化等方面表现出良好的应用前景。由于氨基的强亲和力作用，因此氨基功能化金属有机配位聚合物在应用中越来越受到重视。本文从MOFs的概念、结构特点、常见合成方法以及其应用进行了阐述。并以NH2-BDC以及Zn(NO3)2 采用溶剂热法合成氨基功能聚合物IRMOF-3，利用X-射线单晶衍射、热重及红外光谱对该配合物的结构和热稳定性进行了表征。

Abstract
Metal Organic coordination polymer which is also known as Metal Organic framework materials (Metal Organic Frameworks， MOFs) is a kind of porous crystalline materials， due to its special characteristic， such as， its high specific surface area， pore structure functional， and so on， it is attracting public attention.” MOFs in such aspects as gas absorption， separation and catalysis shows a good application prospect”. Owing to the effect of strong affinity of the amine， amino functional metal organic coordination polymer is more and more attention in the applications. This thesis explain the concept of MOFs， general synthesis methods， structure characteristics， and its application. The synthesis of amino functional polymer IRMOF – 3 from NH2-BDC with Zn(NO3)2 using solvent hot method ，and X-ray single crystal diffraction， thermogravimetric (tg)， and ir spectra of the complexes had been used to characterize the structure and thermal stability.
Key words: MOFs; Metal Organic Frameworks; amino; functional
