摘要：

The photochemistry of xanthone complexed with cyclodextrins (alpha-, beta- and gamma-CD) in the solid state has been examined by diffuse reflectance laser flash photolysis. The first half-life for xanthone triplet decreases as the size of the CD cavity increases; long-lived ketyl radicals are observed in the cases of beta- and gamma-CD. These changes in photobehavior are attributed to the restrictions on the mobility of included xanthone imposed by the CD structure.
