Our purpose is to develop a nitroxide-based ESR probe for singlet oxygen.Among the new anthracenyl nitroxides 1-4 prepared, nitroxide 1 is the most useful. 1 reacts with singlet oxygen to give endoperoxide 18 quantitatively in organic solvents as well as when 1 is incorporated in the bilayers of DMPC vesicles.The reaction is sufficiently rapid an the resulting changes in the ESR spectra are sufficiently characteristic so that the conversion of 1 into 18 may serve as an ESR-based probe for singlet oxygen.
