The formation of non-covalent electrostatic complexes based on the water-soluble fullerene derivative (WSFD) and chlorin e6, dissolved in water or in ethanol was showed by absorption and fluorescent spectroscopy methods. As a result of the formation of such complexes, the chlorine e6 absorption spectrum changed with a bathochromic shift and its fluorescence was effectively quenched. The Stern-Volmer constants of complex are 7.3·10^5 and 2·10^5 M^-1 in water and ethanol, respectively. It was found that complex consists of 1 molecule of WSFD and 3 dye molecules in aqueous solution, while in ethanol this ratio is 1:1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
