Fluorescent Signaling of Oxone by Desulfurization of Thioamide

Abstract

The chemosignaling of the oxidant Oxone by selective desulfurization of a thioamide was Investigated. Pyrene-thioamide was efficiently converted to its amide analogue by reaction with Oxone, resulting in a pronounced fluorescent turn-on type signaling. Selective signaling of Ozone in aqueous solution was possible in the presence of representative alkali and alkaline earth metal ions, as well as common anions.
