含多活性中心的氢键镧系金属有机骨架材料的构建及其识别催化性质研究

HOFs and MOFs are favored by many chemists as two new types of porous materials. Each of these two materials has its own unique and excellent properties, but also has some disadvantages. In order to realize the complementary advantages of the two materials and make up for their respective performance defects, the project plans to combine MOFs and HOFs to construct lanthanide HMOFs by using coordination bonds and hydrogen bonds. It can not only improve the stability of structure of HOFs so that the hydrogen bonding sites can be fully utilized, but also can solve the disadvantages of MOFs materials single active site. In addition, the luminescent and catalytic characteristics of the lanthanides can be fully utilized. This project intends to introduce HOFs hydrogen bonding nodes into lanthanide MOFs and cooperate with metal nodes to construct HMOFs with multiple active sites and to explore their applications in recognition and catalysis. This study will help address the limited application of HOFs due to their poor stability and the single identification of poor catalytic performance due to the active site of MOFs. It also provides new ideas and new methods for the design of HMOFs with excellent properties and novel structures.

氢键有机骨架HOFs与金属有机骨架MOFs作为两类新型的多孔材料受到很多化学工作者的青睐。这两种材料各自具有其独特的优良性能，同时也存在一些缺点。为了实现两种材料的优势互补，弥补各自的性能缺陷。本项目计划将MOFs和HOFs相结合，利用配位键、氢键共同作用来构筑稀土氢键金属有机骨架HMOFs材料。既可以充分利用HOFs结构的氢键位点，又可以提高普通MOFs材料功能化活性位点单一的弊端，同时能够充分利用稀土元素在发光、催化方面的特性与优势。我们拟将氢键活性位点引入到稀土MOFs中，与MOFs金属位点以及功能客体相互协同，构筑多活性中心的HMOFs材料并探索其在识别催化方面的应用。该研究将有助于解决HOFs中氢键的充分利用问题以及MOFs活性位点单一带来的识别催化效率、灵活性不高的问题，也为设计合成性能优异、结构新颖的HMOFs材料提供新思路与新方法，同时在含多活性中心协同功能位点多孔材料的应
