A 2D bilayered metal-organic framework as a fluorescent sensor for highly selective sensing of nitro explosives



A 2D bilayered metal-organic framework as a fluorescent sensor for highly selective sensing of nitro explosives



Dalton Transactions 44(17): 7822-7827



A novel Cd-MOF (metal organic framework) [Cd3(NTB)2(DMA)3]·2DMA (H3NTB = 4,4',4''-nitrilotrisbenzoic acid; DMA = N,N-dimethylacetamide) () was obtained under solvothermal conditions. The resulting MOF exhibits a novel (2D→3D) interdigitated architecture that is obtained from a bilayered motif with hexagonal grids. Luminescence properties of the activated phase of well dispersed in different solvents have also been investigated systematically, which demonstrate distinct solvent-dependent luminescence spectra with emission intensities significantly quenched toward nitrobenzene (NB) and 2,4,6-trinitrophenol (TNP). The results reveal that can be applied as a fluorescent sensor for the detection of TNP with high sensitivity, selectivity, and recyclability.
