Abstract: | A new colorimetric and fluorimetric chemosensor for F- detection based on 1H-imidazo4,5-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. |
