摘　　要：合成了13种1,5-双(1′-苯基-3′-甲基-5′-吡唑啉酮-4′)-戊二酮-[1,5](BPMPPD)和溴化十六烷基吡啶盐(CPB)的稀土配合物.研究了配合物的红外光谱、紫外可见光谱、差热-热重谱、荧光光谱、核磁共振谱及摩尔电导等性质,发现配合物属离子型缔合物CP+[Ln(BPMPPD)_2]-.Pr、Nd、Ho、Er、Tm配合物发生超灵敏跃迁.配合物的热分解温度具有“四分组”效应,Sm、Eu、Tb、Oy为线性荧光。Thirteen new solid complexes have been synthesized and characterized by elemental analysis , molar conductivity, IR spectra, UV spectra, thermoanalysis, fluorescence spectra etc. The stoi-chiometry of complexes are CP[Y (BPMPPD)2] · 5H2O, CP[La (BPMPPD)2] 2H2O, and CP[Ln (BPMPPD)2] (Ln = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb). The results of ther-moanallysis show that the decomposition temperature of the coordination compounds has the 'tetraef-fect'. The hypersensitive transition of Pr, Nd, Ho, Er, Tm complexes and characteristic fluorescence of Sm, Eu, Tb, Dy complexes have been studied.
