摘要：
Novel europium(RI) complexes, (2-pyrazinecarboxylato)(phenanthroline) europium(III) [Eu(pzc)(3)(phen)] and (5-methyl-2-pyrazine-carboxylato) (phenanthroline)europium(III) [Eu(mpzc)(3)(phen)] have been designed and synthesized. These complexes were characterized by FT-IR, UV-Vis, and X-ray photoelectron spectroscopy. Photoluminescence (PL) studies showed that the two complexes emitted remarkably red luminescence. When powder samples of Eu(pzc)(3) (phen) and Eu(mpzc)(3) (phen) were examined using time-resolved spectroscopic analysis, the luminescence lifetimes were found to be 1.05 and 2.36 ms, respectively. Thermogravimetric analysis showed that the europium complexes possessed good thermal stability up to 345-350 degreesC. (C) 2004 Elsevier B.V. All rights reserved.
