dc.description.abstract | Dichlorofluorescein derivatives with two aza-crown ether binding units were prepared by the Mannich reaction and their chemosensing behaviors toward transition metal ions were investigated. An 18-crown-6 ether derivative exhibited pronounced Cu2+-selective fluorescence signaling, with selectivity over other common physiologically important alkali, alkaline earth and transition metal ions. The compound also displayed 1:1 complex formation with Cu2+ ion, with a detection limit of 2.9 x 10(-6) M in an aqueous 50% DMSO solution at pH 7, showing that it may offer potential as a chemosensor for the detection of submillimolar Cu2+ ions in physiological environments. A 15-Crown-5 ether analogue also revealed selective Cu2+ signaling, although with somewhat diminished selectivity compared with its 18-crown-6 counterpart. (C) 2009 Elsevier Ltd.
