抄録

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