We demonstrate that photoactivated oxygen addition to diphenylanthracene moities can be used as a tool for protection of porphyrin's phosphorescence against oxygen quenching. Phosphorescent palladium(II) tetrabenzoporphyrin, covalently linked to four diphenylanthracene moieties, was synthesized and studied. Upon irradiation with ambient light or red laser in solution in air, addition of oxygen and formation of the corresponding endoperoxides were observed. Heating of the irradiated samples afforded the parent porphyrin material.
我们证明，向二苯基蒽部分光活化添加氧可作为一种工具，用于保护卟啉磷光免受氧猝灭。合成并研究了与四个二苯基蒽部分共价连接的磷光钯（II）四苯并卟啉。在空气中溶液中用环境光或红色激光照射时，观察到氧的添加和相应内过氧化物的形成。加热辐照后的样品得到母体卟啉材料。
