Abstract
An extensive spectroscopic study of the amylose-Rose Bengal complex in aqueous solution has been undertaken in order to explain the physical and chemical mechanism of the complexation phenomenon. UV-visible abs orption, fluorescence, and optical rotatory measurements provided info rmation on the complex formation. Two mechanisms, one connected with s tructural changes of amylose induced by Rose Bengal and the other conn ected with the formation of the nonfluorescent complex of amylose and Rose Bengal, have been found and are discussed quantitatively. A simpl e model for amylose-Rose Bengal complex formation has been proposed.
