Distinct Approach

1O2 oxidation of a non-fluorescent sulfoxide forms a fluorescent sulfone, with significant (>50-fold) increase in emission. The oxidation occurs via intramolecular oxygen atom transfer from a reactive persulfoxide intermediate. This represents a new, mechanistically-distinct approach to fluorescent 1O2 detection.
