Abstract

A novel organic ligand, 6-paramethylaniline carbonyl 2-pyridine carboxylic acid (Hp-MAP), and the corresponding europium complex, tris(6-paramethylaniline carbonyl 2-pyridine carboxylato) europium(III) (Eu-p-MAP) have been designed and synthesized. The results showed that Eu-p-MAP was a conjugated complex, emitting remarkably strong red luminescence. The lifetimes of ⁵D₀ of Eu³⁺ in the complex were examined using time-resolved spectroscopic analysis; the lifetime values were 0.72±0.01 ms for 1.0×10^-5 moll^-1 Eu(p-MAP)₃ ethanol solution and 1.16±0.01 ms for solid of Eu(p-MAP)₃, respectively. Thermogravimetric analysis showed the europium complex had good thermal stability.
