|
摘要
选用具有不对称结构的1,3-二酮苯甲酰丙酮(HBA)和Eu Cl3·6H2O合成了一种新的β-二酮稀土配合物,通过紫外光谱、红外光谱、元素分析、热重分析等方法对这种配合物进行了结构表征,得到了苯甲酰丙酮Eu(Ⅲ)配合物的推测结构,同时,对其进行了荧光性能的测定,荧光结果表明,苯甲酰丙酮Eu(Ⅲ)配合物显示了铕的特征光谱,具有良好的荧光性能。
A new Eu( Ⅲ) complex has been synthesized and designed by reactions of benzoylpropanone and Eu Cl_3·6H_2O. The complex was characterized by a number of analytical techniques. Meanwhile,the luminescence of the complex has been investigated. The result shows that benzoylpropanone europium( Ⅲ) complex has good luminescence property.
