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。
The ligand BPOP and its europium complexes Eu2 (BPOPB) 3.H2O were synthesized. Elemental analysis, IR, UV-Vis absorption, 1H-NMR characterization. Through the analysis of infrared and ultraviolet visible spectrum, the results show that the rare earth ion Eu3 + and the ligand coordination occurred. The fluorescence spectra of the complexes at different concentrations were studied and the phenomenon of concentration quenching was found with the peaks of the excitation spectra and the maximum excitation wavelength shift.
