Abstract

The invention provides a metal organic framework material based on biomolecules and its preparation method and application. The general formula of the metal organic framework material is {(X) a [Zn b (L 1 ) c (μ d -O) e (L 2 ) f ]} n , where: X is the counter ion, L 1 Is the first ligand, the first ligand is purine or purine derivatives, L 2 is a second ligand, and the second ligand is an amino-containing carboxylic acid. The present invention adopts the functional chemical modification of the carboxylic acid ligands, endows the ligands with fluorescent properties, and creates more structural and functional possibilities for the subsequent framework; by introducing the second ligand purine or purine derivatives , can realize the friendliness to the environment and biological samples; the material reported in the present invention is simple and easy to operate in the synthesis method, presents regular pores in the structure, and can realize the specificity and sensitivity detection of formaldehyde in the 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...
