杜醌自由基光化学路径的CIDEP研究
A CIDEP study on the photochemical route of duroquinone radicals
摘要
Abstract
The CIDEP spectra of the transient radicals in the photolysis of duroquinone(DQ)/ ethylene glycol(EG) system in acid, basic and micellar environment were measured with the homemade 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 with pH=9 or 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 with pH=2.5 was irradiated, the CIDEP signal of DQH· appeared. These experimental results indicate that the neutral radical DQH· was formed through the proton transfer from EG to 3DQ* and DQ·- was formed from the dissociation of DQH· accompanying polarization transfer.关键词
