近年来,以二氰蒽(DGA)为敏化剂对烯类化合物进行光敏氧化研究颇受重视。Foote等曾对此作过系统工作,他们从热力学、闪光光解以及对氧化产物进行分析等方法确认其间存在着电子转移。最近Steichen等指出:二氰蒽也可做为单线态氧敏化剂在光氧化反应中发挥作用。可以认为二氰蒽作为敏化剂兼有电子转移和能量转移的能 In recent years, the photosensitizing oxidation of alkene compounds with dicyanocamphene (DGA) as sensitizer has received much attention. Foote et al. Have systematically worked on this, and they confirm the existence of electron transfer between thermodynamics, flash photolysis and the analysis of oxidized products. Recently, Steichen et al. Indicated that dicyan-anthracene can also act as a singlet oxygen sensitiser in photooxidation. It is believed that as a sensitizer, dicyan-anthracene combines both electron transfer and energy transfer
