摘要
The inclusions of methylene blue and phenothiazine by beta-cyclodextrin (beta-CD) in sodium dodecyl sulfate (SDS) micelles and SDS/n-C5H11OH mixed micelles are studied by fluorescence spectroscopy. beta-CD molecules can include monomers of methylene blue only after they have included SDS at a ratio of 1:1. However, phenothiazine can be included in the beta-CD cavities even with beta-CD concentrations lower than the total SDS concentration in SDS micelles, but not for solutions with SDS/n-C5H11OH mixed micelles.
