| Abstract: | A novel organic ligand, 6-(ortho-methyl-anilino carbonyl) 2-pyridine carboxylic acid (H-o-MAP), and the corresponding europium complex, tris(6-(ortho-methyl-anilino carbonyl) 2-pyridine carboxylato) europium (Ⅲ) (Eu-o-MAP) were designed and synthesized. The results show that solid Eu-o-MAP is a conjugated complex, emitting strong red fluorescence dominantly due to a ligand-sensitizd luminescence mechanism. The lifetimes of 5D0 of Eu3+ in the complex were examined using time-resolved spectroscopic analysis, and the lifetime values were (1.50±0.01) ms for solid Eu(o-MAP)3 and (1.10±0.01) ms for 1.0×10-5 mol*L-1 Eu(o-MAP)3 ethanol solution, respectively. Thermogravimetric analysis shows that the europium complex has good thermal stability. |
