摘　　要：以2,5-吡啶二羧酸、磷钼酸和稀土金属钕盐为原料,采用水热法合成了一种多酸配合物。通过红外、紫外、荧光、循环伏安、热重分析等对其进行了表征。结果表明,配合物在波长为370 nm激发下,在458 nm处有很强荧光发射峰。热重分析表明其具有较好的稳定性;电化学性质研究表明,在-0.3~0.3 V电势范围内,配合物具有氧化还原性能。A novel neodymium compound which were synthesized with 2,5- pyridine carboxylic acid and phosphomolybdic acid as ligand was obtained via a hydrothermal synthesis method. This compound was characterized by element,IR spectroscopy,fluorescence and cyclic voltammetry,theromogravimetric analysis. Under excitation of 370 nm UV light at ambient temperature,strong fluorescent emission was observed at 458 nm. In the potential range of- 0. 3 ~0. 3 V,electrochemical properties of the complex were researched,and it showed obvious electrochemical activity within the scope of this potential.
