— Electronically excited triplet species generated during the peroxidase catalyzed aerobic oxidation of appropriate substrates efficiently elicit fluorescence from acceptors in micelles, as shown with 9, 10‐dibromoanthracene and chlorophyll solubilized by various surfactants. In the case of 9, 10‐dibromoanthracene excited by triplet acetone, phosphorescence also can be detected near O 2 depletion. The significant implications of this study are that micelle‐solubilized chlorophyll is an excellent detector of enzyme‐generated triplet carbonyl species, as confirmed with several systems, and that the use of micelles make it possible to extend ‘photobiochemistry without light’ to other photobiologically important, yet water insoluble acceptors.
