A rare 3D chloro-laced Mn(II) metal-organic framework to show sensitive probing effect to Hg2+
Abstract
Two 3D Mn(II) metal-organic frameworks (MOFs), [Mn(L-Cl)(DMA)](H2O) (1) and Mn(L-CH3)(DMA) (2) (H2L-Cl = 2,2'-dichloro-4,4'-azodibenzoic acid, H2L-CH3 = 2,2'-dimethyl-4,4'-azodibenzoic acid) were synthesized under similar solvothermal condition. Both MOFs crystallize in the orthorhombic system and show the 3D rod-packing networks in 2-fold interpenetrated pattern with sra topology. Due to the different substituent laces of MOFs (-Cl vs -CH3), only MOF 1 shows highly selective and sensitive fluorescence sensing effect for detecting Hg2+ ion.
