Hg2+-Selective OFF−ON and Cu2+-Selective ON−OFF Type Fluoroionophore Based upon Cyclam

A new cyclam derivative having two different fluorophores of pyrene and NBD subunits was prepared, and its Hg2+- and Cu2+-selective signaling behaviors were investigated. The detection limits for the analysis of Hg2+ and Cu2+ ions were found to be 7.9 × 10-6 and 2.6 × 10-7 M in aqueous acetonitrile...

Summary:A new cyclam derivative having two different fluorophores of pyrene and NBD subunits was prepared, and its Hg2+- and Cu2+-selective signaling behaviors were investigated. The detection limits for the analysis of Hg2+ and Cu2+ ions were found to be 7.9 × 10-6 and 2.6 × 10-7 M in aqueous acetonitrile solution (H2O−CH3CN = 10:90, v/v), respectively. The compound also exhibited a selective Hg2+/Cu2+-induced OFF−ON−OFF type of signaling pattern that can be utilized for the construction of functional supramolecular switching systems.
