A Fluorescent In (III) Metal-Organic Framework for Explosives Detection
A novel metal-organic framework {[In3(TATAT)2]·3CH3NH3·7NMF·8H2O}[JLU-MOF101, H6TATAT=5,5′,5″-(1,3,5-triazine-2,4,6-triyl) tris-(azanediyl)triisophthalate, NMF=N-methylformamide] with cor topology has been synthesized under solvothermal conditions. The framework of JLU-MOF101 is constructed by {In(COO)4}− nodes and a hexacarboxylic organic ligand. JLU-MOF101 exhibits excellent fluorescence properties in N, N-dimethylformamide(DMF) solution, and its emission spectrum can be greatly overlapped with the ultraviolet absorption spectra of trinitrophenol(TNP) and 2,4-dinitrophenol(2,4-DNP). As a result, JLU-MOF101 exhibits excellent performance of fluorescence quenching for TNP and 2,4-DNP. In addition, we demonstrate the selective detection capability of JLU-MOF101 through a large number of anti-interference tests.
