A dual channel fluorescence chemosensor for anions involving intermolecular excited state proton transfer

Kihang Choi, Andrew D. Hamilton

Research output: Contribution to journalArticle


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.
