Abstract

Effects of the photolytically generated naphthoquinone radicals in the solutions containing different surfactants were studied by using the time-resolved ESR spectroscopy. In the ethylene glycol solvent the CIDEP effects of the naphthosemiquinone radical and ethylene glycol ketyl radical after irradiation at 308nm were observed due to triplet mechanism (TM). In the TX-100 micelle solution, the signals of the spin polarization of the naphthoquinone anion were observed, which was attributed to the electron transition between the polarized triplet of the naphthoquinone and TX-100 micelle.

Key words: CHEMICALLY INDUCED DYNAMIC ELECTRON POLARIZATION (CIDEP), ELECTRON SPIN RESONANCE SPECTROMETRY, FREE RADICAL, NAPHTHOQUINONE, PHOTOLYSIS, MICELLE, SURFACTANTS, ELECTRON TRANSFER REACTION
