过氧化苯甲酰(BPO)的光诱导分解曾为许多工作者所注意。Walling和Gibian认为:以二苯酮为敏化剂时,BPO的敏化光解是通过三重态的能量转移过程。Encinas和Lissi则认为敏化是通过单重激发态使激发能转移至过氧化物基态的热振动态,从而导致过氧化物的分解。Tokumarur是最早提出过氧化苯甲酰光敏化诱导分解过程中存在着激基复合物(Exciplex)的可能性。最近他们又进一步研究以BPO为猝灭剂去猝 Photoinduced decomposition of benzoyl peroxide (BPO) has attracted the attention of many workers. Walling and Gibian that: sensitizers with benzophenone, BPO sensitized photolysis through the triplet energy transfer process. Encinas and Lissi think that sensitization is the thermal vibrational state that transfers excitation energy to the peroxide ground state through the singlet excited state, resulting in the decomposition of peroxide. Tokumarur was the first to propose the possibility of Exciplex in the benzoyl peroxide photosensitization-induced decomposition process. Recently, they further study to BPO as a quencher to quench
