摘要：
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 150 ms, which could not be affected by various coexisting anions, even F-. Futher studies showed that the detect limit was as low as 2.05 x 10(-7) M, and the binding constant was determined to be 1.02 x 10(8) M-1. Due to these unique properties, the chemosensor showed potential application in intracellular imaging. (C) 2015 Elsevier B.V. All rights reserved.
