Abstract

The invention relates to an ionic rare-earth metal organic coordination polymer and a preparation method thereof. The coordination polymer is obtained in a way that carboxyl-functionalized ionic liquid brominated 1, 3-diacetate imidazole is taken as bridging ligand and reacts with ethanol and water mixed solvent. The coordination polymer has potential ion exchange function, catalytic function and gas storage function and has a great value of application in the field of material science.

Description

[0001] Field of the invention: the present invention relates to an ionic rare earth metal organic coordination polymer and a preparation method thereof. Background of the invention: [0002] Metal-organic coordination polymers or metal-organic frameworks (MOFs) are a new class of porous materials that have attracted extensive attention in the academic community in the past decade. Porous coordination polymers have the characteristics of plastic structure, high porosity, and uniform pore size distribution. They have excellent performance and application prospects in heterogeneous catalysis, host-guest molecular exchange, and separation of biomacromolecules. They may also be used in high-selectivity Molecular storage, magnetic control, nonlinear optics and other aspects of molecular storage, as the "candidates" for new materials. This type of material is a complex with a highly regular infinite network structure formed by self-assembly between metals or metal clusters and ligand...
