A mechanistically-distinct approach to fluorescence visualization of singlet oxygen

Author affiliations

Abstract

We describe fluorescence detection of 1O2 by a new strategy. Oxidation of a non-fluorescent sulfoxide by 1O2 occurs via intramolecular oxygen atom transfer in a reactive persulfoxide intermediate. The resulting sulfone shows significantly enhanced (>50-fold) emission. This approach complements known methods, and is being extended to biological 1O2 imaging.
