A novel organic ligand, 6-aniline carbonyl 2-pyridine carboxylic acid (HAP), and the corresponding europium complex, tris(6-aniline carbonyl 2-pyridine carboxylato) europium (III) (Eu-AP) have been designed and synthesized. The results showed that Eu-AP was a conjugated complex, emitting strong red luminescence. The lifetimes of D-5(0) of Eu3+ in the complex were examined using time-resolved spectroscopic analysis, and the lifetime value was 0.55 +/- 0.01 ms for solid Eu(AP)(3). Thermogravimetric analysis showed that the europium complex had good thermal stability.
