• Hg2+ and Cu2+ selectivity
• chemosensor
• dioxocyclam
• anthracene
• fluoroionophore

New dioxocyclam derivatives bearing two anthracene fluorophores were prepared, and their fluoroionophoric properties toward transition metal ions were investigated. Chemosensor 2 having anthrylacetamide moieties exhibited pronounced Hg2+ and Cu2+-selectivefluoroionophoric properties in aqueous acetonitrile solution over other representative transition metal ions, as well as alkali and alkaline earth metal ions. Chemosensor 2 also exhibited Hg2+ and Cu2+ selectivity under competitive conditions in the presence of physiologically and environmentally important metal ions. The detection limits for the sensing of Hg2+ and Cu2+ ions were 7.8 x 10(-6) and 1.5 x 10(-6) M, respectively, in aqueous 95% acetonitrile solution.
