Abstract

The invention relates to the technical field of polyacid crystalline molecule metal complexes, in particular to a polyacid crystalline molecule with a zinc complex as well as a preparation method and an application of the polyacid crystalline molecule. Rigid expanded organic molecules 1, 2-di (4-pyridyl) ethylene are selected as a bridging reagent, and life-necessary metal zinc ions and Keggin type polyacid are combined together; the polyacid crystalline molecule with the zinc complex is successfully prepared under the assistance of ammonium metavanadate and a surfactant polyethylene glycol 400, and the molecular formula of the polyacid crystalline molecule is determined to be [Zn(bpe) (PW12O40)]2bpe.2H2O. According to the invention, colorimetric research on peroxidase-like catalytic oxidation is carried out by adopting polyacid modified by a Zn-containing complex for the first time, the zinc-containing complex is used for detecting biological small molecules, and research results show that zinc complex functionalized polyacid crystalline molecules show good peroxidase-like activity; the peroxidase-like compound can be used as a novel peroxidase-like catalyst for detecting biological small molecules.

Description

technical field [0001] The invention relates to the technical field of polyacid crystalline molecular metal complexes, in particular to a polyacid crystalline molecule with zinc complexes and its preparation method and application. Background technique [0002] As a vital part of various metabolic processes in the human body and the entire life process, small biological molecules, their content in the body directly affect the health of the human body; when their concentration in the body changes abnormally, it will cause a series of disease. In organisms, dopamine (DA), ascorbic acid (AA) and uric acid (UA) are a class of very important bioactive small molecules that play key roles in physiological processes such as blood circulation and metabolism in the central nervous system. The occurrence of diseases is closely related to the content of these biomolecules. Among them, AA is a vitamin that can protect the body from the attack of oxidative substances, and can prevent and...
