| 摘要: 本文通过修饰邻香草醛芳环上羟基的方法,得到两种Schiff碱配体:N,N'-二(2-氧乙酸-3-甲氧基)苄叉乙二胺(H2L1)和N,N'-二(2-氧乙酸-3-甲氧基)苄叉1,3-丙二胺(H2L2),利用水热合成方法以新合成的配体为基点设计合成了2个新的六配位Schiff碱锌(Ⅱ)配合物[Zn(L1)]·7H2O(1)和[Zn(L2)]·7H2O(2),通过元素分析、红外光谱和核磁共振光谱等测试手段对配合物进行了表征,并用X射线单晶衍射测得Zn(Ⅱ)配合物的晶体结构。X射线晶体学研究表明两种配合物晶体结构中都包含多个溶剂水分子,配合物1是以Zn(Ⅱ)为中心扭曲的三方棱柱构型,配合物2是以Zn(Ⅱ)为中心扭曲的八面体构型。初步研究了两种配合物的固体发光性,结果表明这两种配合物具有良好的光致发光的性能,有望在光学材料方面得到应用。 |

| Abstract: We synthesized two novel Schiff-Base ligands by modificating the aromatic aldehyde: H2L1=N,N'-bis(2-oxy-acetate-3-methoxyl)benzylpropylene diamine, H2L2=N,N'-bis(2-oxy-acetate-3-methoxyl)benzylpropylene (1,3-propane)diamine. [Zn(L1)]·7H2O (1) and [Zn(L2)]·7H2O (2) complexes were prepared by the reaction between H2L1, H2L2 and zinc salts in the solvents of water. The two complexes were structurally characterized by elemental analysis, IR, HNMR and single-crystal X-ray diffraction. The X-ray diffraction results suggest that both the two complexes contain lattice water molecules. The complex 1 exhibits distorted tri-prism geometry and the complex 2 exhibits distorted octahedron geometry. There are lattice water molecules in the complex 1 and 2. In this paper, we research the solid luminescence of these two complexes. The results suggest that they have excellent photoluminescence and will be useful in the optical material.
