The features of AAA adsorbed on the ethylatedβ-CD polymer were similar with those of the parentalβ-CD polymer, but theadsorption ratios of AAA on the ethylatedβ-CD polymer were higher than those of the parentalβ-CD polymer. It may be due to the strengthened hydrophobic interactions between AAA and the ethylatedβ-CD polymer, which was caused by the ethylation of the parentalβ-CD polymer.

Based on the changes in the spectrum characters of guest molecules producedthrough inclusion complex formation with cyclodextrins, we have carried out two aspects of investigation:First, the mechanisms for the host-guest recognition reactions have been studied, such as the interactions between 3-CD and curcumin, the main constituent of the rhizomes of the plant Curcuma longa, the recognition of p-CD towards rubidate, the effective component of the Chinese traditional medicine madder, and the reactions of p-CD towards the antileprotic drug dapsone and the antiinflammatory drug nabumetone: The formation of supramolecular complex between P-CD and guest molecule has been discussed and verified in virtue of multitudinous means such asultraviolet-visible absorption, fluorescence emission, infrared spectrogram and so on. The influence of addition of linear alcohols on the supramolecular system has been studied and the reason why the noncovalent interactions in the three-component system could result in a decrease in the apparent association constant of the inclusion complex has been revealed.
