摘要(Abstract)：

分别以2-氰基-3-(4-(二苯胺)苯基)丙烯酸(TPA-1)、2-氰基-3-(5-(4-(二苯胺)苯基)-噻吩-2-基)丙烯酸(TPA-2)和2-氰基-3-(5'-(4-(二苯胺)苯乙烯基)-[2,2'-联噻吩]-5-基)丙烯酸(TPA-3)为配体合成了3个稀土配合物Nd(L)3·2H2O(L=TPA-1,TPA-2,TPA-3)。采用元素分析、核磁共振氢谱(1H NMR)、红外光谱(IR)对配合物的组成进行了确认。通过紫外-可见吸收光谱和荧光光谱的测定,研究了配体共轭链长度对配合物吸光和发光性能的影响。结果表明:配体共轭链长度的增加有效增大了配合物的摩尔吸光系数,拓宽了配合物的吸光范围。配合物固体粉末近红外发光测试表明,Nd(TPA-1)3·2H2O和Nd(TPA-2)3·2H2O在889,1063和1339 nm处有较强的发射峰,分别归属于Nd(III)4F3/2→4I9/2,4F3/2→4I11/2和4F3/2→4I13/2的特征跃迁。
