Synthesis and Fluorescence Properties of Mixed Ligand Complex of Eu(Ⅲ) with 1,2,4,5-Benzenetetra Carboxylic Acid and 1,10-Phenanthroline
【摘要】 在乙醇和水的混合溶剂中 ,合成了 Eu( )与 1,2 ,4,5—苯四甲酸 (H4TCB)及 1,10—邻菲咯啉混配配合物。通过元素分析、热谱分析和摩尔电导确定其化学组成为 Eu4/3 (TCB) (phen)· 4H2 O,并利用红外光谱、紫外光谱和 X射线粉末衍射对配合物进行了表征。研究了配合物的荧光性质
【Abstract】 The novel mixed ligand complex of Eu(Ⅲ) with 1,2,4,5-benzenetetracarboxylic acid and 1,10-phenanthroline has been synthesized in mixed solvents of ethanol and water.The complex has the constitution of Eu 4/3 (TCB)(phen)·4H 2O as characterized by elemental analysis,molar conductance,IR,UV,X-ray powder analysis,TG and DTA techniques.The fluorescence intensity of Eu 4/3 (TCB)(phen)·4H 2O was found to be enhanced by in corporation of the synergistic ligand 1,10-phenanthroline.
