The fluorescence quenching of 3-(2-naphthoxyl)-1-aminopropane (<B>1</B>), 3-(1-naphthoxyl)-1-aminopropane (<B>2</B>), and 3-(2-dibenzofuranoxyl)-1-aminopropane (<B>3</B>) by β-cyclodextrin (β-CD)-bound viologens is much more efficient than that by dimethyl viologen. The binding studies of the guests with β-CD and lifetime measurements of the quenching indicated that this is due to the static quenching in complexes formed by inclusion of the aromatic guests into β-CD moiety of the β-CD- viologens.
