The invention relates to the technical field of fluorescent probes, and provides a metal organic framework material, the structural unit of which is Eu(DTA) 1.5 (H 2 O)]·H 2 O, wherein DTA is 2,5-bis(1H-imidazol-1-yl) terephthalate; the metal-organic framework material belongs to the triclinic system, space group, has a tsf-type three-dimensional topology, and is in a three-dimensional framework There are uncoordinated nitrogen and oxygen atoms in . When utilizing the material provided by the invention to carry out Fe 3+ Or when nitrobenzene is recognized, after the uncoordinated nitrogen and oxygen atoms in the molecule combine with it, the nitrogen and oxygen atoms with electron-donating ability can transfer their electrons at the highest energy level to the fluorescent group in the excited state The electron orbits vacated by the group prevent the electrons excited by light from directly transitioning to the original ground state orbitals to emit fluorescence, which leads to fluorescence quenching, thus achieving the realization of Fe 3+ or the identification of nitrobenzene.
