- 論文の詳細を見る
The photooxygenation of dibenzo[<I>a</I>,<I>j</I>]perylene by visible light irradiation was studied spectroscopically. The structure of unstable photooxygenation product was deduced from spectroscopic data and results of MO calculations to be as 8,12b-endoperoxide of dibenzo[<I>a</I>,<I>j</I>]perylene. This endoperoxide released oxygen gradually at room temperature, recovering the original hydrocarbon. The activation energy for this dark reaction was determined to be 21.4±0.5 kcal/mol in benzene and 22.6±0.5 kcal/mol in ethanol.
