Abstract

A macrocycle containing an aminocoumarin fluorophore showed two different fluorescence emission bands on binding with certain anions. Proton transfer from the fluorophore excited state occurred depending on the basicity of the bound anion (see scheme, A-: anion) and this new pathway makes more-sensitive anion sensing possible.
