摘　　要：以2,6-吡啶二羧酸和硅钨酸为配体合成了一种新型的稀土金属配合物,并对其进行了红外光谱、紫外光谱、荧光光谱、热重、电化学等表征。结果表明,该配合物在196nm和253nm处具有较强的紫外吸收峰;在624nm处有一个很强的荧光发射峰;热稳定性较好;在-0.25~0.2V（vs.SCE）的电势范围内有一对氧化还原峰,具有良好的电化学活性。A novel rare earth metal complex was synthesized using 2,6-pyridinedicarboxylic acid and silicotungstic acid as ligands,and the prepared complex was characterized by FTIR,UV,fluorescence,thermal gravimetric and electrochemical analysis.Results showed that the complex had strong UV absorption peaks at 196 nm and 253 nm,strong fluorescence emission peak at 624nm;the complex had good thermal stability and a pair of redox peak in potential range of-0.25~0.2V（vs.SCE）which showed its good electrochemical activity.
