Photooxidation of the anthracene 1 and alkene 3 traps in a particle/solution dispersion via 669-nm irradiation of Si-Pc or e6 particles in D2O. The particle surface is wetted and solution-phase 1O2 is generated at the sensitizer particle surface. Evidence for a reaction of 1O2 with 1 is the formation of endoperoxide 2 (quantified by the disappearance of a peak at 378 nm), and with 3 is the formation of hydroperoxide 4 (quantified by the appearance of the hydroperoxide peaks at Hb, Hc, and Hd by 1H NMR).
