A new fluorescein derivative bearing a boronic acid group as a fluorescent chemosensor for fluoride ion

Abstract

A new fluorescein derivative 1 bearing a boronic acid group was investigated as a fluorescent chemosensor for F-. An off-on type fluorescence enhancement was observed by the blocking of the photoinduced electron transfer mechanism, which was induced by the interaction between fluoride and boronic acid moiety. © 2006 American Chemical Society.
