摘要：

Three lanthanide complexes of 4-acyl pyrazolone derivatives: Ln(PMPP-SHZ)(2)(CH3OH)(2) (Ln = Sm (1), Eu (2), Gd (3); PMPP-SHZ = N-(1-phenyl-3-methyl-4-propionyl-5-pyrazolone)-salicylidene hydrazide) have been synthesized and structurally characterized by X-ray crystallography. And all of them were carefully investigated by elemental analysis, thermal analysis and spectral characterization. The fluorescence of these three complexes 1-3 in solid state was investigated at room temperature. All complexes emit a blue emission band, and there are three characteristic emission peaks of Sm3+ evidently and one characteristic emission peak of Eu3+. (c) 2007 Elsevier B.V. All rights reserved.
