【摘要】 通过苦味酸制成苦味酸钾，然后将2,2’-联吡啶、氯化铽、苦味酸钾依次溶解，混合回流，生成苦味酸2,2’-联吡啶合铽(Ⅲ)。经紫外、傅立叶红外、循环伏安法、扫描电镜观察等手段对苦味酸2,2’-联吡啶合铽(Ⅲ)进行表征，并测定其荧光性质。本实验使用的溶剂为混合溶剂(无水甲醇∶无水乙醇=1∶1)。氯化铽、2,2’-联吡啶、苦味酸钾摩尔比为1∶2∶3。从紫外光谱图和荧光光谱图可以看出稀土铽(Ⅲ)配合物中表现出中心离子铽(Ⅲ)的桥梁作用的特性。更多还原

【Abstract】 Potassium picrate is prepared from picric acid, then 2,2’-bipyridyl, terbium chloride, potassium picrate successively dissolved and mixed reflux generate picric acid 2,2’-bipyridine co-terbium(Ⅲ). By UV, FTIR, cyclic voltammetry, scanning electron microscopy and other means of picric acid 2,2’-bipyridine co-Tb(Ⅲ) were characterized and tested for fluorescence properties. The solvent used in this experiment was a mixed solvent(anhydrous methanol∶ethanol=1∶1). Terbium chloride, 2,2’-bipyridyl, potassium picrate molar ratio of 1∶2∶3. From the UV spectra and fluorescence spectra can be seen Terbium(Ⅲ) complexes exhibit central ion terbium(Ⅲ) as a bridge.更多还原
