Abstract:

Massive release of metal cations and nitro-aromatic explosives causes a serious threat to the environment and human health, and their efficient detection is of great research significance and challenge. Metal-organic frameworks(MOFs) are considered as a promising fluorescence sensing detection platform. A Eu-MOF material, [(CH32NH22[Eu6μ3-OH)8(EDDC)6]·8DMA·3MeOH·6H2O[JLU-MOF128, H2EDDC=(E)-4,4′-(ethene-1,2-diyl)-dibenzoic acid], with fcu topology, was synthesized under solvothermal conditions. The structure and composition of JLU-MOF128 were characterized by single crystal X-ray diffraction, powder X-ray diffraction, X-ray photoelectron spectroscopy, infrared spectroscopy, elemental analysis and thermogravimetric analysis. Owing to the introduction of the fluorescent H2EDDC ligand, JLU-MOF128 exhibits significant fluorescence properties. The metal cations and nitro-aromatic compounds detection results indicate that JLU-MOF128 is an ideal multi-induction fluorescence sensor with good fluorescence detection performance for Fe3+, 2,4,6-trinitrophenol(TNP), and 2,4-dinitrophenol(2,4-DNP) in NN-dimethylformamide(DMF), with Ksv values of 2.09×104, 8.49×104 and 5.75×104 L/mol, and detection limits of 5.99, 1.51 and 1.93 μmol/L, respectively.
