A Cu(2+ )ion-selective fluoroionophore with dual off/on switches

A new malonamide fluoroionophore possessing two pyrene moieties was synthesized. This bispyrene exhibited the fluorescence of the pyrene monomer (λ(em )= 395 nm) and intramolecular excimer (λ(em )= 467 nm) emissions. The designed derivative showed the excellent ion sensing ability to Cu(2+). The &qu...

Sumario:A new malonamide fluoroionophore possessing two pyrene moieties was synthesized. This bispyrene exhibited the fluorescence of the pyrene monomer (λ(em )= 395 nm) and intramolecular excimer (λ(em )= 467 nm) emissions. The designed derivative showed the excellent ion sensing ability to Cu(2+). The "on-off-off" and "off-on-off" fluorescence responses were demonstrated by the addition of the variable Cu(2+ )concentration. The utilization of the dual off/on responses could apply to the estimation of the rough Cu(2+ )concentration.
