摘要
以邻(间、对)苯二甲酸和1,10-邻菲啰啉(phen)为配体,合成了5种Eu(Ⅲ)的三元配合物.通过EDTA配位滴定分析和元素分析确定了各配合物的组成.利用红外光谱分析对配合物的结构进行了初步表征,在配合物中羧基氧原子和phen中的氮原子均参与了配位.采用TG-DTG技术对配合物的热稳定性进行了研究,5种配合物均有较好的热稳定性.在室温条件下,测定了各固体配合物的激发和发射光谱.
Five ternary complexes of Eu(Ⅲ) were synthesized with o(m,p)-phthalate as the first ligand,and 1,10-phenanthroline(phen) as the second ligand.They were characterized by elemental analysis,IR and TG-DTG methods.In these complexes,the metal ions were bonded to the oxygen atoms of carboxylate and the nitrogen atoms of phen.The TG-DTG analysis showed that these complexes were thermally stable.The excitation and luminescence spectra were carried out at room temperature.
