A Zn(II)-based polyrotaxane 1D coordination polymer, {[Zn(Or)(Bimb)(H2O)]2·2H2O}n, 1 (Or = orotate; Bimb = 1,4-bis[(1H-imidazol-1-yl)methyl]benzene), has been synthesized. 1 provides for luminescent sensing of acetone, Fe3+, MnO4–, nitrofurantoin (NFT), uric acid (UA), and sucrose. The coordination polymer displays exceptional intensity quenching of ∼96.1% with 200 mg/dl of sucrose in aqueous solution. In addition, the reactivity of 1 to photocatalytically degrade the organic dye methylene blue (MB), a hazardous organic pigment, was established. 1 was able to degrade the dye due to the generation of reactive oxygen species.
