Ratiometric Fluorescent Chemosensor for Silver Ion at Physiological pH
Bis-pyrene derivative 1, bearing two pyrene and pyridine groups, was synthesized as a ratiometric fluorescent chemosensor for Ag+ in aqueous solution. Fluorescent chemosensor 1 displayed a selective ratiometric change with Ag+, which was attributed to the excimer−monomer emissions of pyrenes. A mech...

Zusammenfassung: | Bis-pyrene derivative 1, bearing two pyrene and pyridine groups, was synthesized as a ratiometric fluorescent chemosensor for Ag+ in aqueous solution. Fluorescent chemosensor 1 displayed a selective ratiometric change with Ag+, which was attributed to the excimer−monomer emissions of pyrenes. A mechanism for the binding mode was proposed based on fluorescence changes, NMR experiments, and theoretical calculations. |
