Abstract
The photodimerization of 2-anthracenesulfonate in water was accelerated in the presence of β- and γ-cyclodextrins (CyDs). While four configurational isomers of the photodimer were obtained in the presence of γ-CyD with similar ratio of the yields to that in the host-free solution, only one of the isomers was obtained in the presence of β-CyD. The results were explained by the formation of two guest-one host inclusion complex in the former case and of two guest-two host inclusion complex in the latter. No evidence of an inclusion complex with α-CyD was obtained. The inclusion effects of CyD on the photodimerization of other water-soluble anthracenes were also examined.
