Anion recognition and sensing by a new macrocyclic dinuclear copper(II) complex: a selective receptor for iodide.
A macrocyclic dinuclear copper complex, [Cu(2)(II)(1)Br(3)(H(2)O)]Br, has been synthesized and characterized by X-ray crystallography, in which the macrocycle is folded to form a bowl-shaped cavity. The sensing ability of the receptor has been studied for halides by UV-vis spectroscopy in water-acetonitrile (1:3, v/v) and water. The results indicate that the new receptor exhibits a strong affinity and selectivity for iodide.
