摘　　要：Eu(Ⅲ) complexes with bipyO2 ligand were intercalated into the interlayer spacing of montmorillonite (MMT) by solid-solid ion exchanging and coordination reaction of bipyO2 with the Eu3+ ion existing in the interlayer spacing of Eu-MMT at room temperature, respectively. The obtained luminescent supramolecular composite materials, Eu(bipyO2)4Cl2+-MMT and Eu(bipyO2)43+-MMT were characterized by elemental analysis, XRD and FTIR spectroscopy. At the same time, the luminescent properties of the materials were also studied. The results show that the intercalation assembly materials have regular layered structures and good luminescent properties. They emit characteristic red emissions of Eu3+ strongly under ultraviolet light excitation. The relative luminescence intensities of the unit mass of Eu3+ of intercalation assemblies are much better than that of the corresponding pure Eu3+ complex possibly due to the rigid layered structures of the materials and the supramolecular interaction between the host layers and the guest complex ions.Eu（Ⅲ） complexes with bipyO2 ligand were intercalated into the interlayer spacing of montmorillonite （MMT） by solid-solid ion exchanging and coordination reaction of bipyO2 with the Eu^3 ＋ ion existing in the interlayer spacing of Eu-MMT at room temperature, respectively.
