Three CPs [Zn2 (PDA)2 (BMIOPE)2 ·3H2 O]n (1), [Co(Br-BDC)(BMIOPE)]n (2) and [Co(MIP)(BMIOPE)]n (3) were synthesized by solvothermal method based on dual-ligand strategy (H2 PDA, Br-H2 BDC, BMIOPE and H2 MIP are 1,3-phenylenediacetic acid, 5-bromo-isophthalic acid, 4,4'-bis(2-methylimidazol-1-yl)diphenyl ether and 5-methylisophthalic acid, respectively). Complexes 1 and 3 exhibit twofold parallel interwoven sql nets. Complex 2 is 2D layer structure. The luminescence property investigations showed that complexes 1-3 could act as multi-responsive fluorescent sensors to detect UO2 2+ , Cr2 O7 2- and CrO4 2- and nitrofurantoin (NFT) through fluorescence turn-off process, presenting excellent sensitivity and selectivity...
