title: Photosensitization with alpha-terthienyl: the formation of superoxide ion in aqueous media.
abstract: It is well known that alpha-terthienyl generates singlet oxygen in organic solvents with high quantum yields. In an aqueous medium, the production of superoxide radical-anion is readily detected by comparing the reduction of ferricytochrome c or nitro blue tetrazolium in the presence and in the absence of superoxide dismutase. Electron transfer reactions from the electronically excited sensitizer are also detected in an argon atmosphere.
