Abstract A stable three-dimensional coordination polymer, [Eu2(pbbp)(pbsd)3] (1) (H2pbsd = 2,2′-((1,4-phenylenebis(methylene))bis(sulfanediyl))dinicotinic acid, H2pbbp·2Cl = 1,1′-(1,4-phenylene-bis(methylene))-bis(3-carboxy pyridinium) dichloride), was prepared by the solvothermal reaction of Eu(NO3)3·6H2O, H2pbbp·2Cl and H2pbsd in mixed solvent of DMF and H2O, which was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, infrared spectroscopy, and thermogravimetric analyses. 1 exhibits a 3D 6-connected sqcl network decorated by uncoordinated Lewis basic thioether groups. In particular, 1 shows excellent application as luminescent sensor for sensing Ag+ ions in ethylene glycol solution with high sensitivity and selectivity based on luminescence quenching effect.
