Three novel Zn-based coordination polymers (CPs), [Zn(MIPA)] (), {[Zn(MIPA)(4,4'-bipy)(HO)]·1.5HO} (), and {[Zn(MIPA)(bpe)]·HO} () (MIPA = 4-methoxyisophthalic acid, 4,4'-bipy = 4,4'-bipyridine, bpe = (E)-1,2-di(pyridine-4-yl)ethane), were constructed by ligand 4-methoxyisophthalic acid under solvothermal conditions. Compound features a beaded 2D-layer architecture, while compound presents a 2-fold interpenetrating structure with a uninodal three-connected topology. Compound has a 3-fold interpenetrated four-connected topology. Photoluminescence investigations of compound were explored in detail, by which ions were detected, and it was observed to have the highest quenching efficiency toward Al and S ions. The possible fluorescence quenching mechanisms of toward Al and S ions were also explored. To the best of our knowledge, this is the first potential dual-responsive luminescent probe based on a Zn(II) coordination polymer for detecting Al and S ions via a luminescence quenching effect in ethanol.
