| 摘 要： | 采用溶剂热方法合成了两种具有良好发光性能的d-f异核金属配合物EuZn(C8H7O3)5(phen)(H2O)(1)和TbZn(C8H7O3)5(phen)(H2O)(2). 采用单晶X射线衍射表征了晶体结构. 结果表明, 两种配合物是同构的, 在配合物中, Zn为五配位, Ln(Ⅲ)Ln(Ⅲ)=Eu, Tb]为八配位. 金属间通过对甲氧基苯甲酸根的羧基(—COO)基团成桥联结. 测定了配合物的紫外-可见吸收光谱、 红外光谱和荧光光谱. 讨论了配位环境对荧光性质的影响以及配合物分子内能量传递问题.

| Abstract: | Two d-f heterometallic coordination complexes EuZn(C8H7O3)5(phen)(H2O)(1) and TbZn(C8H7O3)5(phen)(H2O)(2) were synthesized with hydrothermal reaction. These two complexes exhibit strong luminesecent emission. The crystal structures of the two complexes were determined via X-ray diffraction. The two complexes are isomorphic. Zn(Ⅱ) ion is five-coordinated and Ln(Ⅲ) ion is eight-coordinated. Zn(Ⅱ) and Ln(Ⅲ) ions are bridged by 4-methoxybenzoic acid ligands. The UV-Vis-NIR, IR and fluorescence spectra of the complexes were measured. The influence of coordination environment on the luminescence property and intramolecular energy transfer of complexes were discussed. |
