Abstract

A new rhodamine-based fluorescent probe RSP was facilely synthesized. Interestingly, the RSP-Hg-ClO4 ensemble can serve as a selective fluorescent probe for iodide and bromide based on metal ion removal and anion ligand exchanging, which is a novel rhodamine-based fluorescence sensing mechanism. Moreover, RSP can recognise Hg2+ selectively in 99% aqueous solution.
