Three novel ligands containing pyridine-2,6-dicarboxylic acid unit, trans-4 -(4'-methoxystyryl) pyridine-2,6-dicarboxylic acid, trans-4-(4'-(dimethylamino)styryl)pyridine-2,6-dicarboxylic acid, and trans-4-(4'-(diphenylamino)styryl)pyridine-2,6-dicarboxylic acid were synthesized and their complexes with Eu(III), Tb(III) ions were successfully prepared. The ligands and the corresponding metal complexes were characterized by means of MS, elemental analysis, IR, (1)H NMR and TG-DTA. The luminescence spectra of Eu(III) and Tb(III) complexes in solid state were studied. The strong luminescence emitting peaks at 615 nm for Eu(III) and 545 nm for Tb(III) can be observed. The applications in cell imaging of the europium and terbium complexes were investigated.
合成了三种新型配体，分别为含有吡啶-2,6-二羧酸单元的反式-4-(4'-甲氧基苯乙烯基)吡啶-2,6-二羧酸、反式-4-(4'-(二甲氨基)苯乙烯基)吡啶-2,6-二羧酸和反式-4-(4'-(二苯基氨基)苯乙烯基)吡啶-2,6-二羧酸，并成功制备了它们与 Eu(III)、Tb(III)离子的配合物。通过 MS、元素分析、IR、(1)H NMR 和 TG-DTA 对配体和相应的金属配合物进行了表征。研究了固态下 Eu(III)和 Tb(III)配合物的发光光谱。可以观察到 Eu(III)的强发光发射峰在 615nm 处，Tb(III)的在 545nm 处。研究了铕和铽配合物在细胞成像中的应用。
