Abstract

Abstract The application of time-resolved emission spectroscopy to the characterization of cyclodextrin inclusion complexes of pyrene in the presence of various alcohols is described. Such measurements offer a means of selectively studying the characteristics of inclusion complexes in the presence of uncomplexed pyrene. The fluorescence lifetimes and formation constants of these complexes are enhanced in the presence of alcohols. These enhancements are reportedly due to the formation of pyrene-alcohol-CD ternary complexes.
