Abstract

The invention discloses a rare earth metal organic framework material with antibacterial activity and a preparation method thereof. The chemical formula of the rare earth metal organic framework material is C14H11N3O8Nd, and the rare earth metal organic framework material is prepared by taking 1, 4-bis (imidazole-1-yl) terephthalic acid, 2, 6-pyridine dicarboxylic acid and Nd(NO3)3.6H2O as raw materials and adopting a solvothermal method. The rare earth metal organic framework material prepared by the invention has a relatively strong bacteriostatic effect on escherichia coli (G-), so that therare earth metal organic framework material can be used for preparing a bacteriostatic agent for preventing and treating escherichia coli.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to a rare earth metal organic framework material with antibacterial activity and a preparation method thereof. Background technique [0002] At present, rare earth metal-organic frameworks (Ln-MOFs) have attracted much attention due to their unique photoelectromagnetic, catalytic, thermal stability properties and topological structure, and have broad application prospects. They have made considerable achievements in the fields of chemistry, synthesis, and materials research. Huge progress, but the application in the fields of pharmacy, biology and medicine is still less. [0003] 1,4-bis(imidazol-1-yl)terephthalic acid ( , HBTA), is a newly synthesized nitrogen heterocyclic compound, which has certain fluorescence activity, has the advantages of nitrogen heterocyclic compounds and aromatic polycarboxylic acids, and has rich N and O coordination sites. Rare earth (Ln...
