multi-functional roles such as an emission component, a photodimerization component, and a leaving group. When the light irradiation was performed under an oxygen atmosphere, photo-oxidative PC bond cleavage to leave the antharacenyl group was observed. Moreover, phosphonyl radical was produced and then PP bond formation to form diphosphane was observed.
已经合成了作为光敏化合物的蒽基(二苯基)氧化膦和双蒽基苯基氧化膦。这些化合物的蒽基基团指示多功能作用,例如发射组分,光二聚化组分和离去基团。在氧气氛下进行光照射时,观察到光氧化性的P C键断裂而离开了蒽基。此外,产生了膦酰基自由基,然后观察到形成P P键以形成二膦烷。
