Abstract

A novel organic ligand, 6-parachloroaniline carbonyl 2-pyridine carboxylic acid, and the corresponding europium complex, tris(6-parachloroaniline carbonyl-2-pyridine carboxylate) europium (III) have been designed and synthesized. The results showed that the synthesized product was a conjugated complex, emitting remarkable strong red luminescence, and was a good red luminescence material with good thermal stability. The 5D0 lifetime of Eu3+ in the complex was examined using time-resolved spectroscopic analysis. The lifetime values for 1.0 × 10-5 mol/l ethanol solution of the complex and for the complex solid were 0.49±0.01 and 1.94±0.01ms, respectively.
