✦ Synopsis
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 absorption, fluorescence, and optical rotatory measurements provided information on the complex formation. Two mechanisms, one connected with structural changes of amylose induced by Rose Bengal and the other connected with the formation of the nonfluorescent complex of amylose and Rose Bengal, have been found and are discussed quantitatively. A simple model for amylose-Rose Bengal complex formation has been proposed. * Amylose-Rose Bengal Complexes, Part I.
