2-benzanthracenes and other polycyclic hydrocarbons, when irradiated either in bulk aqueous suspensions or in the comparable excess phase under mixed surface films, were converted rapidly by ultraviolet light to photo-oxides. When held in two-dimensional solution or molecular association with sterols in mixed surface films at the air-water interface, the hydrocarbons were protected from such photodecomposition
某些烷基-1,2-苯并蒽和其他多环烃,当在大量水悬浮液中或在混合表面膜下的相当过量相中照射时,会被紫外光迅速转化为光氧化物。当在二维溶液中或在气-水界面的混合表面膜中与甾醇分子缔合时,碳氢化合物不受这种光分解。在可以进行比较的一种情况下,光氧化伴随着烃与甾醇膜相互作用能力的丧失。
