- A novel colorimetric and fluorescent iminocoumarin-based turn-off chemosensor for acetate ion was designed and synthesized. The chemosensor could fast detect acetate ion in a 1:1 ratio within 150ms, which could not be affected by various coexisting anions, even F⁻. Futher studies showed that the detect limit was as low as 2.05×10⁻⁷M, and the binding constant was determined to be 1.02×10⁸M⁻¹. Due to these unique properties, the chemosensor showed potential application in intracellular imaging.
