内容記述 |
We have studied nanosecond kinetics of the hydrated electron (e(aq)(-)) generated by laser excitation of phenothiazine (PTH) in the presence of quinone in SDS solution using FT EPR. Using two different quinones, idebenone (IDB) and CoQ(0), we have observed the unique photochemical processes due to the micellar effect in the system. The analyses of FT EPR results suggested that IDB with the long alkyl alcohol chain at the 6-position became the corresponding anion radical by quenching of e(aq)(-) On the other hand, CoQ(0), without the long chain, was reduced by two processes, quenching of e(aq)(-) and direct electron transfer from the triplet precursor. Moreover, the distinctive dispersive pattern, which implied the radical pair of [PTH.+...e(aq)(-)], was observed at 30 ns after the excitation of PTH in IDB/SDS micellar system but was not observed for CoQ(0). |
