摘　　要：合成了配体BPOP及其铕的配合物Eu2(BPOPB)3.H2O。采用元素分析,红外,紫外可见吸收,1H-NMR表征。通过分析红外和紫外可见光谱,结果表明,稀土离子Eu3+与配体发生了配位。研究了配合物在不同浓度下的荧光光谱,发现了浓度焠灭现象,并伴随着激发光谱分峰和最大激发波长位移现象。BPOPB and Eu2（BPOPB） 3·H2O were synthesized. The ligand and the corresponding Eu^3＋ complex were characterized by elemental analysis, and FT-IR, UV-absorption and ^1H-NMR spectroscopy. Analysis of the IR spectra and UV spectra suggested that Eu^3＋ ion was coordinated to the ligand BPOPB. The fluorescence properties of the complex in DMF solvent at different concentrations were investigated and it was discovered that the Eu3 ＋ ions could be sensitized by the ligand. The excited spectrum of the complex in different concentrations shows that the maximal excited wavelength could be solited and shifted.
