Abstract

The CIDEP spectra of transient radicals during photolysis of the duroquinone (DQ)/ethylene glycol (EG) system in acid, basic, and micellar environments were measured with a home-made highly time-resolved ESR spectrometer. In the DQ/EG homogeneous solution, the enhanced emissive CIDEP signal of the neutral durosemiquinone radical DQH• was observed. When the DQ/EG solution at pH 9 or the DQ/EG/TX-100/H2O micelle system was photolyzed, the CIDEP signal of the duroquinone anion radical (DQ•−) was obtained. When the DQ/EG solution at pH 2.5 was irradiated, the CIDEP signal of DQH• appeared. These experimental results indicate that the neutral radical DQH• was formed by proton transfer from EG to 3DQ*, and that DQ•− was formed by dissociation of DQH• accompanying polarization transfer.
