Photoinduced electron transfer was studied in a supramolecular complex assembled by an electron-donating substrate (N-(1-naphthylacetyl)-1-adamantanamine (1)) and an electron-accepting receptor (p-nitrobenzoyl-β-cyclodextrin (NBCD)), which was stabilized by hydrophobic interactions in water/methanol (9 : 1) binary solvents. Fluorescence quenching results indicated that the electron transfer process occurred in a intra-supramolecular system. The electron transfer reactions of 1- or 2-naphthyl acetate with NBCD were also studied, and upward Stern-Volmer curves were obtained. It is concluded that two different electron transfer pathways, intra-supramolecular and inter-molecular electron transfer processes, exist.
