摘要: Three novel ligands containing pyridine-2,6-dicarboxylic acid unit, trans-4 -(4'-methoxystyryl) acid, trans-4-(4'-(dimethylamino)styryl)pyridine-2,6-dicarboxylic and trans-4-(4'-(diphenylamino)styryl)pyridine-2,6-dicarboxylic were synthesized their complexes with Eu(III), Tb(III) ions successfully prepared. The the corresponding metal characterized by means of MS, elemental analysis, IR, (1)H NMR TG-DTA. luminescence spectra Eu(III) in solid state studied. strong emitting peaks at 615 nm for 545 can be observed. applications cell imaging europium terbium investigated.
