Chromofluorescent Probes for Selective Detection of Fluoride and Acetate Ions

Chromofluorescent probe 2 has been developed for selective and ratiometric estimation of F- (CH3CN) ions. The presence of a lipophilic dodecyl appendage at imidazolium nitrogen in 3 successfully allows the selective determination of AcO- ions in protic (CHCl3-MeOH, 1:1) solvent.
