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, 1H 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.
