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)3 phen.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4 F3/2→4I9/2,4F3/2→4I11/2及4F3/2→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)3 phen的HOMO/LUMO能级为-5.81/-2.44 eV.
A novel neodymium complex Nd (OXD) 3 phen with 2-(5-phenyl-1,3,4-oxadiazol-2-yl) phenol (OXD) and 1,10-phenanthroline (phen) as ligands was prepared,and it was characterized by FTIR,UV-Vis,photoluminescence (PL).The FTIR results showed that the ligands OXD and phen coordinated to the Nd3+ ion successfully.Under excitation at 370 nm,the complex showed near infrared PL emission bands at 869,1058 and 1355 nm,which could be ascribed to the transitions of 4F3/2→4I9/2,4F3/2→ 4I11/2and 4F3/2→4I13/2 from Nd3+ ion,respectively.In addition,the highest occupied orbital (HOMO) and the lowest unoccupied orbital (LUMO) energy levels of Nd (OXD) 3phen were characterized and determined to be-5.81 and-2.44 eV,respectively,by means of cyclic voltammetry (CV).
