Abstract Two 3D Mn(II) metal-organic frameworks (MOFs), [Mn(L-Cl)(DMA)](H 2 O) ( 1 ) and Mn(L-CH 3 )(DMA) ( 2 ) (H 2 L-Cl = 2,2’-dichloro-4,4’-azodibenzoic acid, H 2 L-CH 3 = 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 –CH 3 ), only MOF 1 shows highly selective and sensitive fluorescence sensing effect for detecting Hg 2+ ion.
