α-Alkyldibenzylketones included in cation exchanged faujasite type zeolites show photobehavior different from that in isotropic organic solvents. Rearrangement and disproportionation which do not contribute in solution are the major processes within the cavities of faujasites. Cation size plays a major role in controlling the pathway pursued by the primary and the secondary radical pair.
阳离子交换八面沸石中包含的α-烷基二苄基酮的光行为不同于各向同性有机溶剂。在溶液中不起作用的重排和歧化是八面沸石腔内的主要过程。阳离子的大小在控制主要和次要自由基对所遵循的途径中起着重要作用。
