摘要(Abstract)：

合成了一种N,O-型配体2-(5-苯基-1,3,4-噁二唑)苯酚(OXD),以其作第一配体、邻菲罗啉(phen)作第二配体制备了一种新型的钕配合物Nd(OXD)_3phen。通过傅里叶变换红外谱(FTIR)、元素分析、紫外可见吸收光谱(UV-Vis)、激发和发射光谱以及循环伏安(CV)法等手段对其结构和性能进行了表征;实验结果表明:配体和中心离子配位良好,在370 nm光激发下,配合物在869,1058和1355 nm处有典型的Nd3+离子发射峰,分别对应于Nd3+离子的~4F_(3/2)→~4I_(9/2),~4F_(3/2)→~4I_(11/2)及~4F_(3/2)→4I13/2跃迁。另外,通过CV曲线及紫外吸收光谱可以推算出Nd(OXD)_3phen的HOMO/LUMO能级为-5.81/-2.44 e V。

关键词(KeyWords)： 稀土配合物;近红外发光;N,O-配体
