摘要: The stoichiometry of molecular complexation anthracene-2-sulfonate (AS) with hexakis-, heptakis and octakis-(6-amino-2,3-di-O-methyl-6-deoxy)cyclodextrins (α-, β- γ-PACDs) has been investigated by UV, fluorescence, circular dichroism spectrophotometry; in neutral alkaline media only β-PACD gives the 2 : inclusion complex, while sufficiently acidic all PACDs form complexes benefitting greatly from electrostatic interactions. relative rates for PACD-promoted photodimerization are closely related to modes.
