英文摘要

A tripodal tris(urea) ligand with 2,2′-bipyridyl (bpy) substituents (L) has been designed and synthesized, which coordinates with three equivalents of Ru(bpy)2Cl2·2H2O, followed by treatment with NH4PF6, to afford the anion receptor [(bpy)6Ru3L](PF6)6 (1). The anion-binding behavior of the ligand L and the RuII–bpy functionalized receptor 1 toward different anions was investigated by 1H NMR (for L and 1), fluorescence, and UV-vis spectroscopy (for 1). Both compounds showed selective recognition of SO42− or H2PO4 ions in the 1 : 1 binding mode in the NMR studies. The RuII complex 1 displayed the metal-to-ligand charge transfer emission at 600 nm, which was quenched on addition of the sulfate and dihydrogen phosphate ions. Quantitative fluorescence titration experiments were carried out and the stability constants (log K) of the complex 1 with SO42− and H2PO4 ions were obtained to be 4.73 and 4.69 M−1 (1 : 1 binding mode), respectively.
