A new Ni coordination polymer [Ni(MIP)(BMIOPE)] () was constructed (BMIOPE = 4,4'-bis(2-methylimidazol-1-yl)diphenyl ether, and HMIP = 5-methylisophthalic acid), possessing two-dimensional (2D) twofold parallel interwoven net structure with a 4∙6 point symbol. Complex has been successfully obtained based on mixed-ligand strategy. The fluorescence titration experiments revealed that complex could act as multifunctional luminescent sensor to simultaneously detect UO, CrO and CrO, and NFT (nitrofurantoin). The limit of detection (LOD) values for complex are 2.86 × 10, 4.09 × 10, 3.79 × 10 and 9.32 × 10 M for UO, CrO, CrO and NFT. The K values are 6.18 × 10, 1.44 × 10, 1.27 × 10 and 1.51 × 10 M for NFT, CrO, CrO and UO. Finally, the mechanism of its luminescence sensing is studied in detail. These results manifest that complex is a multifunctional sensor for sensitive fluorescent UO, CrO, CrO and NFT detection.
