摘要：

The quenching of uranyl-ion fluorescence by adamantylideneadamantane and its photosensitized oxidation products (adamantilideneadamantan-1,2-dioxetane and adamantanone) in acetone solutions was studied. Possible mechanisms of the uranyl-photocatalyzed degradation of dioxetane are discussed. The photochemical quantum yield of dioxetane (phi = 0.55 +/- 0.05) was determined, and an ion-radical oxidation mechanism involving the substrate radical cation and the superoxide ion was proposed.
