Abstract

A new colorimetric and fluorimetric chemosensor for F^- detection based on 1H-imidazo[4,5-b]phenazine derivative has been designed and synthesized. It shows excellent fluorescent specific selectivity and sensitivity for F^- in DMSO solution. Upon addition of F^- to the solution of probe 1, a remarkable color change from yellow to red could be observed easily by the naked-eye. The detection limit of this probe toward F^- is 6.2 × 10^-6 mol/L. Analysis by ¹H NMR proved that the imidazolyl N-H could be hydrogen-bonded with added fluoride anions, and results in the difference of colors.
