摘要：

Two novel Zn(II) coordination polymers (CPs), namely {[Zn-4(EBIDA)(2)(BIMB)(2)]center dot 6H(2)O}(n) (1) and {[Zn-2(EBIDA)(DIB)]center dot H2O}(n) (2), (H(4)EBIDA = 1,1 '-(ethane-1,2-diyl)bis(1H-imidazole-4,5-dicarboxylic acid); BIMB=1,4-bis((1H-imidazol-1-yl)methyl)benzene; DIB=1,4-di(1H-imidazol-1-yl)benzene)) were successfully prepared under hydrothermal conditions using the secondary building unit (SBU) and auxiliary ligand-directed assembly strategies. Both CPs contain the same isolated cage-like [Zn-4(EBIDA)(2)] SBU, and different N-containing auxiliary ligands bridge the SBUs to generate disparate structures. CP 1 shows a 3D catenane framework based on interlocking 1D wave chains formed by semirigid BIMB ligands connecting [Zn-4(EBIDA)(2)] SBUs. CP 2 features a 3D 8-fold interpenetrating diamond network consisting of [Zn-4(EBIDA)(2)] cages and rigid DIB linkers. Investigation of the fluorescence properties revealed that both CPs exhibited strong ligand-based enhanced fluorescence behavior and could be used as multiresponsive fluorescence sensors for selectively detection of Fe3+/CrO42-/Cr2O72-/MnO4- ions and NFT/FZD antibiotics through fluorescence quenching effect with excellent sensitivity (the quenching constant K-SV is almost in the range of 10(3)similar to 10(4) M-1), low limit of detection (the LOD can reach mu M level), strong anti-interference ability and good recyclability. Furthermore, the sensing mechanism of the two CPs for different analytes was investigated. The results showed that competitive absorption was the main reason for the analyte-induced fluorescence quenching of CPs, and photoinduced electron transfer was the secondary cause that antibiotics affected the fluorescence intensity of CPs. This work demonstrated that the structure and properties of CPs containing specific ligand systems can be specifically regulated using crystal engineering techniques and that the as-synthesized CPs crystals have great application potential as fluorescent probes or sensors in the field of environmental protection.
