摘要手性多孔金属有机骨架(MOFs)是由金属离子和含有手性基团的配体通过自组装而形成的具有多孔结构的晶体材料。由于其种类繁多,孔道尺寸大小可调节性以及结构易功能化已经才不对称催化,气体选择性吸附分离以及手性分离等方面展现出了诱人的发展前景。本实验主要是设计合成以L-脯氨酰胺为侧基并分别含有手性O,O-端基和N,N-端基的有机配体,并且选择过渡金属离子(Zn2 +,Fe3+,Co2+)作为次级的连接点与之进行配位,在一定条件下形成单晶,同时在此过程中摸索出最合适的晶体培养条件,表征晶体结构。48455
Chiral porous metal organic framework (MOFs) is a crystal material with porous structure formed by self-assembly of metal ions and ligands containing chiral groups.Due to its various types, the size of the pore size can be adjusted and the structure is easy to be functional, it has been a promising prospect for the development of asymmetric catalysis, selective adsorption, separation and chiral separation. The purpose of my experiment is to design and synthesize two kinds organic ligands with a pendant group of L-prolinamide. One of the organic ligands has a O,O-end groups, the other is N, N- terminal group of chiral organic bridging ligand. next under certain conditions,the use of a ligand end group of a carboxylic acid and nitrogen heterocyclic 3d metal ions (such as Zn2 +,Fe3+,Co2+) to build a single chiral ligands containing porous MOFs. Explore the best growth conditions for crystal, characterize the complex crystal structure.
