Pyridine - Imidazoles Derivatives Synthesis and Performance Research Complexes
Abstract:In pyridine-2,6-dicarbonyl dichloride as raw materials,and with methylene chloride,triethylamine as the solvent,respectively,and dimethyl imidazole, imidazole-2-methanol,imidazole-2-acrylic reaction,synthetic M1,M2,M3,three kinds of ligands,and respectively were prepared with rare earth ions in the Eu(III),Tb(III) complexes.Ligand and the complexes was determined by the IR state of coordination,and the determination of the ligand of M2,M3,uv-vis spectra, fluorescent properties of the complexes were studied,and the two kinds of rare earth ions were determined the position of the maximum excitation wavelength and emission peak.
Key Words:Pyridine-2,6-dicarbonyl dichloride;UV spectrum;Rare earth complexes;Fluorescence characteristics;Infrared spectrum
