Abstract

The invention provides a metal organic framework material based on biomolecules and a preparation method and application thereof. The general formula of the metal organic framework material is {(X) a[Znb (L1) c (mu d-O) e (L2) f]} n, X is a counter ion, L1 is a first ligand, the first ligand is purine or a purine derivative, L2 is a second ligand, and the second ligand is amino-containing carboxylic acid. According to the preparation method, functional chemical modification is carried out on the carboxylic acid ligand, so that the ligand is endowed with a property of emitting fluorescence, and more structural and functional possibilities are created for a subsequently built framework; by introducing the second ligand purine or purine derivative, environmental friendliness and biological sample friendliness can be realized; and the material reported by the invention is simple and easy to operate in synthesis method, has regular pore channels in structure, and can realize specific and sensitive detection of formaldehyde in function.

Description

technical field [0001] The invention belongs to the technical field of porous organometallic materials and environmental monitoring, and in particular relates to a metal organic framework material based on biomolecules, a preparation method of the framework material and an application of the framework material in formaldehyde detection. Background technique [0002] Metal-Organic Frameworks (MOFs) are coordination framework materials composed of metal ions and organic ligands self-assembled. Materials with such structures may not only contain the characteristics of metals and organic ligands, but may also contain metal and organic ligands have new properties. As an emerging porous material with high porosity, high specific surface area, adjustable structure and function, MOFs have been used in some fields such as gas adsorption and separation, small molecule detection, and drug carrier catalysis. Biomolecular-based metal-organic frameworks (BioMOFs), a branch of metal-organ...
