摘　　要：Ternary inclusion complexes β-cyclodextrin （β-CD）, rare earth metal ions （YbC13, YC13）, and 1,8-naphthalene- diamine/ 1,5-naphthalenediamine are synthesized in basic aqueous media, which are characterized via IH NMR and IR spectroscopy. The stoichiometric proportion of β-CD ： YbC13 ： 1, 5-naphthalenedia- mine is 2：1：2, that of β-CD：YCI3 ： 1,8-naphthalenediamine is 2：1：1, and that of β-CD：YbC13 ： 1,8-naphthalenediamine is 2 ： 1 ： 1. The IR spectroscopy of the ternary inclusion complexes in the range of 935-1 000 cm 1 reveals the existence of the coordinate bond M---O or M---N. The possible conformations of the ternary inclusion complexes are depicted.Ternary inclusion complexes β-cyclodextrin （β-CD）, rare earth metal ions （YbC13, YC13）, and 1,8-naphthalene- diamine/ 1,5-naphthalenediamine are synthesized in basic aqueous media, which are characterized via IH NMR and IR spectroscopy.
