摘要
合成了重稀土高氯酸盐甲基苯甲酰甲基亚砜配合物RE(ClO4)3.L5.C2H5OH(RE=Gd,Tb,Dy,Tm,Yb;L=C6H5COCH2SOCH3)。经元素分析、稀土络合滴定、摩尔电导及热重分析确定了配合物的组成,测定了配体及配合物的IR谱、1H NMR及铽配合物的磷光光谱、荧光激发和发射光谱,根据荧光发射光谱数据计算了铽配合物的各能级值。
Abstract RE（ClO4）3·L5·C2H5OH（RE=Gd, Tb, Dy, Tm, Yb; L=C6H5COCH2SOCH3） complexes were synthesized. The composion of the complexes was determined by elemental analysis, coordination titration, molar conductivities, and TGA studies. The ligand and coordination compounds were studied by means of IR spectra, ^1H NMR, and the Tb（ Ⅲ ） coordination compound was studied by means of phosphorescence spectra, and fluorescence excitation and emission spectra. Each energy level of Tb^3＋ was calculated according to the fluorescent emission spectra results.
