合成了3,4-二甲氧基苯乙酸邻菲啰啉钆(Ⅲ)配合物:[Gd2(DMPA)6(phen)2](HDMPA=3,4-二甲氧基苯乙酸,C12H12O4;phen=1,10-邻菲啰啉),并通过元素分析、红外光谱、热重分析对其进行了表征,用单晶X射线衍射方法测定了配合物的晶体结构,晶体属于三斜晶系,空间群P-1。测定了铕离子掺杂的配合物的荧光光谱,荧光光谱表明,游离配体没有荧光,在形成配合物后,显示了铕(Ⅲ)离子的特征发射,在591,618,649和684 nm处观察到了4个分别对应于三价铕离子的5D0→7F1,5D0→7F2,5D0→7F3和5D0→7F4跃迁的特征发射峰,其中以5D0→7F2跃迁的发射最强,这表明配体将吸收的能量有效地转移给了中心离子,配体起到了很好的敏化作用。
Synthesis of 3,4-dimethoxyphenylacetic acid gadolinium (Ⅲ) complexes of phenanthroline: [Gd2 (DMPA) 6 (phen) 2] (HDMPA = 3,4-dimethoxyphenylacetic acid, C12H12O4; phen = 1,10-phenanthroline) was synthesized and characterized by elemental analysis, IR and TG. The crystal structure of the complex was determined by single crystal X-ray diffraction. The crystal belongs to triclinic system , Space group P-1. The fluorescence spectra of europium ion-doped complexes were determined. The fluorescence spectra showed that there was no fluorescence in the free ligands. After the complexes were formed, the characteristic emission of europium (Ⅲ) ions was observed. At 591, 618, 649 and 684 nm, Respectively correspond to the characteristic emission peaks of the 5D0 → 7F1, 5D0 → 7F2, 5D0 → 7F3 and 5D0 → 7F4 transitions of the trivalent europium ions, of which the emission with the 5D0 → 7F2 transition is the strongest, which indicates that the ligand effectively absorbs the energy Transferred to the center ion, the ligand played a very good sensitization.
