Abstract
We report, in this article, a piperidin-4-one derivative carrying pyrenyl fluorescent reporter groups which acts as a Cd2+ ion sensor. The compound is synthesized and characterized using IR and NMR spectral techniques. The compound forms an inclusion complex with β-cyclodextrin. It selectively binds to Cd2+ ions in water and aqueous β-cyclodextrin media. The stoichiometry of the host–guest complex of the compound with β-cyclodextrin is 1:2. The ligand–metal ion binding stoichiometry is 1:1 both in water and in β-cyclodextrin. The linear concentration range of detection of the metal ion is reported. Cyclodextrin complex formation does not affect the metal ion selectivity of the compound.
