Problems solved by technology

[0003] So far, people still face many obstacles in the design and synthesis of nanoporous metal-organic framework materials with large pore size: First, although people can synthesize large-sized and rigid multifunctional organic ligands, due to the -In the synthesis process of organic framework materials, the interpenetration between the framework networks often leads to the reduction or even disappearance of the pore size in many cases to obtain a solid structure. Therefore, the nanoporous metal-organic framework materials designed and synthesized using the ...

Abstract

The invention relates to a nanometer hole metal-organic frame material in a single-level or multilevel pore canal structure as well as a preparation method and the application thereof. The preparation method comprises the following steps: at least one metal salt and at least one polyfunctional group organic ligand reacts with at least one template agent in at least one solvent under the condition that no hole aid agent exists or only one hole aid agent exist, and single-level or multilevel nanometer holes or channels with the size of 0.5-100 nm exist in at least one direction in the internal space of the obtained metal-organic frame solid. The nanometer hole metal-organic frame material with large hole size and the nanometer hole metal-organic frame material in the layered multilevel pore canal structure can be obtained without the synthesis of the large-size organic ligand and have wide applications.

Description

technical field [0001] The invention belongs to a nano-structured organic-inorganic hybrid material, in particular to a nano-hole metal-organic framework material with a single-level or multi-level channel structure inside and a preparation method and application thereof. Background technique [0002] Metal-organic frameworks (MOFs) with nanopores are zeolite-like framework materials with special pore structures synthesized by metal ions and multifunctional organic ligands. Compared with traditional inorganic porous materials such as zeolites, metal-organic framework materials have the characteristics of diverse structures, unique properties, simple synthesis methods, and mild synthesis conditions. , optoelectronic properties, sensors, biological simulation, microreactors, medical diagnosis and treatment, etc. have attractive application potential. There have been many literature reports on the synthesis and application of such materials, such as Zhou Yuanjing et al. in "Jo...
