Abstract

The invention provides a rare earth metal europium-based organic crystalline material, and preparation and application thereof, belonging to the technical field of crystalline materials. The chemical molecular formula of the rare earth metal europium-based organic crystalline material is {[Eu(TATAB)(H2O)2].NMP.H2O}n, wherein n refers to positive infinity and TATAB represents 4,4',4''-s-triazine-1,3,5-tri-m-aminobenzoic acid. A basic unit of a metal frame structure comprises a crystallographically independent Eu<3+> ion and a TATAB ligand; Eu<3+> ions are connected through six oxygen atoms on three TATAB ligands so as to form a double-core basic unit [Eu2(CO2)3]; and double-core basic units are connected via the ligands so as to form a two-dimensional layered network framework. The invention has the advantages that the metal-organic framework material is simple to synthesize and high in crystal purity; the material has a novel structure and has high stability in an organic solvent; and the material can identify iron ions Fe<2+> and Fe<3+> at the same time.

Description

Technical field [0001] The present invention relates to 4,4',4"-s-triazine-1,3,5-tris-m-aminobenzoic acid rare earth Eu metal organic framework material, specifically using triazine polycarboxylic acid as ligand and rare earth metal europium as The metal-organic framework material formed by the metal center, and the compound's fluorescence intensity in a solution system containing different metal ions, can quickly and sensitively identify iron ions of different valence states Fe 2+ And Fe 3+ . Background technique [0002] In recent years, various fluorescent sensing materials have attracted great interest. Among them, lanthanide-metal organic frameworks (Ln-MOFs) have attracted much attention. This is mainly due to the combination of the fluorescence characteristics of lanthanide ions and the pore properties of MOFs. Perfectly combined together. Lanthanide ions, as the metal center of Ln-MOFs, provide them with good fluorescence properties, mainly because the fluorescence of la...
