Tb-N-苯基邻氨基苯甲酸-1,10-菲咯啉二元、三元配合物的合成、表征及荧光性能

合成了稀土Tb-N-苯基邻氨基苯甲酸-1,10-菲咯啉二元、三元配合物。通过元素分析确定二元配合物的组成为TbL₃·4H₂O，三元配合物的组成为TbL₃phen·2H₂O(L: N-苯基邻氨基苯甲酸根，phen: 1,10-菲咯啉)，讨论了两种配合物的谱学性质。通过荧光光谱测试发现，形成的TbL₃·4H₂O二元配合物的荧光强度明显降低，1,10-菲咯啉作为第二配体引入后，使Tb3+的发光强度继续降低，这说明了Tb3+的发光强度与配体的结构有关，通过结构、能量传递和能量匹配对此做了进一步的解释。

Synthesis, Characterization and Fluorescence Properties of Binary and Ternary Rare Earth Complexes with N-Phenylanthranilic Acid and 1,10-Phenanthroline

Some novel binary and ternary complexes of rare earth (Tb) with N-phenylanthranilic acid and 1,10-phenanthroline were synthesized and their compositions were characterized by elemental analysis. The compositions of the complexes have been confirmed to be TbL3. 4H2O and TbL3 phen.2H20 (L: N-phenylanthranilic acid, phen: 1;10-phenanthroline). The spectroscopic properties of the complexes were discussed. The result shows that the luminescence intensities of binary and ternary complexes were decreased by N-phenylanthranilic acid and 1,10-phenanthroline. It is indicated that the intensity of Tb depends on the structure of ligands. The structure, energy transfer and energy matching were studied, and it is concluded that the structure of complex affects the luminescence properties of the complexes.
