2,6-二乙酰基吡啶缩白氨酸铕配合物的合成及荧光性质

The 2,6-diacetylpyridine and the leucine were used to synthesiz a new kind of Schiff base and the complexes of Europium could be formed. The product was identified by Fourier transform infrared spectrometry (FT-IR), element analysis and thermal analysis, and the fluorescent property of the complexes were also investigated. The complexes appear four emission bands 591 nm, 625 nm, 685 nm and 710 nm at wavelength with different intensities at 362 nm wavelength. The width of four emission bands is narrow, thus it has the character of rare earth ion's emission spectra.
