摘　　要：合成了铕的邻菲罗啉配合物,并通过离子交换法将其配阳离子插层组装到了蒙脱土的片层间,制备出了一种超分子复合发光材料[Eu(phen)2(NO3-)]2+-MT。通过红外光谱、X射线衍射、热分析等手段对其进行了表征,并对其荧光性质进行了研究。结果表明,复合材料保持了蒙脱土良好的层柱结构特征,其单位质量稀土配合物的相对荧光强度较相应纯配合物有显著改善,复合材料片层间稀土配合物的热稳定性也较纯稀土配合物有所提高。Complexes of rare-earth europium - 1,10 - phenanthr ware synthesized, the novel supramolecular composite luminescent material was synthesized too, by intercalated the complex into the interlayer space of montmorillonite by ion exchanging. The structures and properties of complexes of Eu^3 ＋ - phenanthr - montmorillonite were characterized by IR, XRD,TG - DTG. At the sac time, the luminescent property of the complexes was also studied. The results show that the intercalated material with regular layered structure. It is also found that the thermal stabilities and relative luminescence intensities of unit Eu^3＋ are distinctly improved after the Eu（ Ⅲ ） complexes are intercalated into the MT.
