Circular dichroism and fluorescence studies of γ-cyclodextrin bearing two naphthyl moieties (<B>1</B>) suggest that <B>1</B> exists as two intramolecular self-complexation forms in water-rich solutions with one or two of the naphthyl moieties included in its cavity. Upon addition of (−)-borneol as a guest, <B>1</B> forms a 1 : 1 host–guest complex, exhibiting slightly diminished excimer and circular dichroism bands. Ethylene glycol converts the intramolecular complexes into a relaxed form, in which two naphthyl moieties dangle outside the cavity.<BR>(<U>Remark: Graphics omitted.</U>)
