Abstract

We report a series of organic fluorophores that undergo selective self-sensitized photooxidation upon light irradiation in air., We report a series of organic fluorophores that undergo selective self-sensitized photooxidation upon light irradiation in air accompanied by a change of fluorescence from yellow to blue on the seconds timescale. The distinct emission changes allow the ratiometric quantitation of O concentration.
