【摘要】 本文合成了两种以1-苯基-3-甲基-4-苯甲酰基吡唑啉-5-酮(PMBP)、乙酰水杨酸(asprin)、1,10-邻菲罗啉(phen)为配体的铽的三元、四元螯合物。通过元素分析、紫外可见光谱、红外光谱确定了它们的组成,并且也研究了其荧光特性。荧光表明:这两种配合物均能发出Tb3+的特征荧光,且四元配合物的荧光强度大于三元配合物的荧光强度。更多还原

【Abstract】 With PMBP , OAcetylsalicy acid and 1,10-phenanthroline as the ligand , the rare earth Tb( III) complexes were synthesized. The composition of the complexes was confirmed by elemental analysis, UV spectro scopic and IR spectra , the fluorescent of ternary complexes were studied. The result of the fluorescence spectre indicate that two complexes can emit characteristic fluorescence of Tb3+ ions and the fluorescence intensity of chelate complexes is highter than that of ternary complexes.更多还原
