设计合成了新的β-二酮配体1-(9-蒽基)-3-三氟甲基-1,3-丙二酮,并与Yb~(3+)和第二配体邻菲罗啉(phen)配位,形成二元配合物YbA_2·2H_2O和三元配合物YbA_3phen,通过元素分析、红外光谱、紫外光谱及荧光光谱对其进行了表征,结果表明,在二元配合物YbA_2·2H_2O和三元配合物YbA_3phen中,都没有出现Yb~(3+)的特征发射峰,配合物的荧光属于配体发光,但是三元配合物YbA_3phen的发光效率要强于二元配合物YbA_2·2H_2O,这与第二配体邻菲罗啉的引入有关。 A new β-diketone ligand, 1- (9-anthryl) -3-trifluoromethyl-1,3-propanedione, was designed and synthesized. (Phen) to form the binary complex YbA_2 · 2H_2O and the ternary complex YbA_3phen, and its structure was characterized by elemental analysis, IR, UV and fluorescence spectra. The results showed that when the binary complex YbA_2 · 2H 2 O and the ternary complex YbA 3phen did not show the characteristic emission peak of Yb 3+. The fluorescence of the complex belongs to the luminescence of the ligand, but the luminescent efficiency of the ternary complex YbA 3phen was stronger than that of the binary complex YbA 2 · 2H 2 O, which is related to the introduction of the second ligand phenanthroline.
