摘要：

A novel organic ligand, 6-diphenylamine carbonyl 2-pyridine carboxylic acid, and the corresponding europium complex, tris(6-diphenylamine carbonyl 2-pyridine carboxylato) europium(III) (Eu-DPAP) have been designed and synthesized. The crystal structure and photoluminescence of Eu-DPAP complex have been studied. The results showed that Eu-DPAP is an electroneutral complex that emits very strong red fluorescence. The lifetime of D-5(0) of Eu3+ in the complex solid was examined using time-resolved spectroscopy, and the value for crystalline Eu(DPAP)3.12H(2)O is 0.69+/-0.01 ms. (C) 2003 Elsevier Ltd.
