The complex stability constants for the inclusion complexation of mono-(6-anilino-6-deoxy)-β- cyclodextrin (1), mono-(6-ethylenediamino-6-deoxy)-β-cyclodextrin (2) and mono-[6-O-(4-carboxyl-phenyl)]- β-cyclodextrin (3) with anionic surfactant sodium dodecyl sulfate (SDS) and cationic surfactant dodecyl trimethyl ammonium bromine (DTAC) were deter-mined by means of fluorescence and UV-Vis titrations in phosphate buffer solution, and their binding modes were investigated by 2D NMR spectroscopy. These results indicate that the introduction of different charge groups on the primary face of cyclodextrins can effectively change the binding abilities of the modified cyclodextrins towards ionic surfactants, and a high selectivity is achieved through the electrostatic interac-tion between host and guest compounds.

Key words: cyclodextrin, surfactant, spectral titration
