Syntheses, structures and fluorescence of lanthanide complexes of 4-acyl pyrazolone derivatives
چکیده انگلیسی

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+.

There are 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 in this article. And all of them were carefully investigated by elemental analysis, thermal analysis and spectral characterization. The analytical data for the newly synthesized complexes indicated that the three complexes were isomorphous with each other, and two-dimensional architecture of the complex is formed via intermolecular hydrogen bond.Figure optionsDownload as PowerPoint slide
