A dinuclear molecular cadmium phosphonate, [Cd-2(H(4)tpmm)(2)(Hpybim)(2)(H2O)(4))center dot 2H(2)O (1.2H(2)O), emitting strong luminescence in both solid-state and suspension phases was synthesized by the reaction of Cd(ClO4)(2), 2,4,6-tris(phosphotylmethyl)mesitylene (H(6)tpmm), and 2-(2-pyridyl)benzimidazole (Hpybim) via the slow diffusion of reactants. Complex 1.2H(2)O showed very poor solubility but high chemical stability in common organic solvents and H2O. Furthermore, 1.2H(2)O also revealed good thermal stability upon heating to 325 degrees C. Luminescence detection on a series of phenolic analytes within 5 min response time showed that bisphenol AF (BPAF) and bisphenol B (BPB) significantly reduced the luminescence intensity of 1.2H(2)O in water, with the quenching efficiencies of 77 and 71%, respectively, while bisphenol Z (BPZ) moderately quenched the luminescence of 1.2H(2)O in water by 52%. The Stern-Volmer quenching constant, K-sv, and the limit of detection (LOD) were determined to be 1931 M-1 and 12.8 mu M for BPAF, 515 M-1 and 14.6 01 for BPB, and 2269 M-1 and 3.0 mu M for BPZ. In addition, 1.2H(2)O behaving as a luminescence sensor has an exclusive detection for BPAF, BPB, and BPZ over a wide range of interfering phenolic analytes, with the exception of dopamine toward BPB. This work demonstrates a highly waterstable molecular cadmium phosphonate suitable for the luminescence detection of bisphenols, endocrinedisrupting chemicals, especially BPAF and BPB, in water.
