抄録

Fluorescent spectroscopic studies on the complexation of naphthalene-appended amino-β-cyclodextrins, 1 and 2, with anionic, cationic, and nonionic surfactants have been carried out. In host 1–surfactant system, an excellent fluorescent signal change was observed. On the other hand, host 2 exhibits no photophysical response in the presence of various surfactants. The difference in the properties between 1 and 2 was interpreted by difference in the inclusion depth of the naphthalene units for the cyclodextrin cavity. The binding abilities and thermodynamic (ΔH°, ΔS°, and ΔG°) quantities of 1–surfactant system have been discussed to characterize structure/enegetics for the complexation process.
