Exclusive fluoride ion recognition and fluorescence “turn-on” response with a label-free DMN Schiff base

Author affiliations

Abstract

A label-free DMN Schiff base (4) has been explored as a highly selective and sensitive fluoride ion receptor. Fluoride-induced deprotonation results in a charge transfer (CT) transition red shifted with a fluorescence ‘turn-on’. Anion selectivity can be tuned by the electron push–pull property of substituents at the phenyl para-position. Selectivity for F is attributed to the suitable acidity of –NH2.
