N2 - Three new sulfone-functionalized coordination polymers, [Mn(L)(DMF)2]n (1), {[Cd3(L)3(DMA)4]·2DMA·4H2O}n (2) and {[Cd3.5(L)4(DMA)(H2O)]·xsol} n (3), where H2L = 5,5-dioxodibenzothiophen-3,7-dicarboxylic acid, have been synthesized under solvothermal conditions and structurally characterized by single-crystal X-ray diffraction. Complex 1 is a 3D framework based on rod-shaped MnII carboxylate chains as secondary building units (SBUs). Complex 2 is a 2D (4,4) net based on linear trinuclear [Cd3(COO)3] clusters (SBUs1), while 3 presents a rarely binodal (4,6)-connected fsc topological net based on linear trinuclear [Cd3(COO)3] clusters (SBUs1) as four-connected nodes and “chairlike” tetranuclear [Cd4(μ3-OH)2(COO)6] clusters (SBUs2) as six-connected nodes, with the Schläfli symbol of (44·610·8)(44·62). Fluorescence measurements reveal that 2 displays excellent luminescence in EtOH and can selectively detect trace amount of nitrofuran antibiotics via luminescence quenching, with high KSV values (1.673 × 104 M−1 for NFT and 2.915 × 104 M−1 for NFZ) and low detection limits (0.39 μM and 0.22 μM for NFT and NFZ). Additionally, the possible mechanisms for the luminescence quenching have been investigated.
