Chromogenic and fluorescent chemodosimeter for detection of fluoride in aqueous solution

Org Lett. 2007 Aug 2;9(16):3109-12. doi: 10.1021/ol0711873. Epub 2007 Jul 13.

Abstract

We have developed a chromogenic and fluorescent chemodosimeter 1 based on the release of resorufin for F- (TBA+ and Na+ salts). This dosimeter 1 displayed drastic dual changes in UV-vis absorption and fluorescence emission intensities selectively for F- over other anions in CH3CN/H2O (50:50, v/v) as well as in acetonitrile.
