合成了铽的配合物[TbL] (ClO4)3(L: 2, 2, 2', 2'-四[N-苯基-N-苄基(乙酰胺)-2-氧甲基]丁醚), 通过离子交换反应将配离子[TbL]3+插层组装到蒙脱土(MMT)层板间, 制备出了新型复合发光材料 [TbL]3+-MMT．用元素分析、X射线衍射、傅氏变换红外光谱和紫外-可见光谱对材料进行了表征, 对其荧光性质进行了研究．结果表明, 复合发光材料保持了蒙脱土良好的层柱结构特征和[TbL]3+离子的笼状结构特征, [TbL]3+离子以单层形式分布于蒙脱土层板间．在紫外光激发下, 复合发光材料发出较强的绿色荧光, 其发射光谱与相应配合物的发射光谱相似．与相应纯配合物比较, 复合发光材料单位质量Tb3+的相对荧光强度、荧光单色性和光稳定性有显著改善, 其激发波长向可见光区发生明显位移, 说明插层组装对相应配合物的激发波长有一定的调制作用.

Tetrapodal ligand L (2, 2, 2', 2'-tetra[N-benzyl-N-phenyl (acetamide)-2-oxymethyl] n-butyl ether) and complex [TbL] (ClO4)3 are synthesized. The complex ion with tetrapodal ligand L, [TbL]3+ is intercalated into the interlayer space of montmorillonite (MMT) by ion exchanging. The obtained luminescent supramolecular composite material, [TbL]3+-MMT is characterized by elemental analysis, X-ray diffraction, Fourier transform infrared spectroscopy, and ultraviolet-visible spectroseopy. At the same time, the luminescent properties of the material are also studied. The results show that the intercalated material with regular layered structure and the interlayer spacing (d001) approximate to the diameter of the complex ion arranged in the interlayer space of the MMT in the formation of a monolayer emit characteristic green emission of Tb3+ strongly under the excitation of ultraviolet light. It is also found that the relative luminescence intensity, the luminescence monochromatic index and the light stability of the intercalated material are distinctly improved after the [TbL]3+ has been intercalated into the MMT. And the excitation wavelength of the complex is modulated till the red shift occurs in the composite material.-
