- Abstract
- New cyclam derivatives having diametrically disubstituted pyrene fluorophores were prepared and their fluoroionophoric properties toward transition metal ions were investigated. The compounds exhibited significant selectivity toward Hg2+ and Cu2+ ions in switching-off type responses in aqueous methanol or acetonitrile solution. Dipyrene-diamide derivative 3, having extra binding sites of the amide function, exhibited more pronounced chemosensing behavior toward Hg2+ and Cu2+ ions than its parent, dipyrene derivative 2. Detection limits for the analysis of Hg2+ and Cu2+ ions of dipyrene-diamide derivative 3 were 1.45 x 10(-6) and 1.30 x 10(-6) M, respectively. The diametrically disubstituted dipyrene-cyclam 2 may be utilized as a new starting platform for the design of other supramolecular fluorescent signaling systems having switching or chemosensing behaviors toward transition metal ions.
