摘要
X-Ray crystallographic studies of beta-cyclodextrin (beta-CD) inclusion complexes with butyrophenone and valerophenone characterize these complexes as 2:2 beta-CD/guest systems with the alkyl chains of the included guest molecules conformationally restricted; the structures explain the reported observation of the modification of the Norrish type II photoreaction for the included aryl alkyl ketones in crystalline beta-CD complexes.
