Three polyether compounds (1-3) which have more than two fluorescent moieties in the both terminals were synthesized, and their complexation properties with Tb3+ were discussed. After formation of complex with Tb3+, sharp fluorescence lines were observed at visible region due to intramolecular energy transfer from xanthene chromophore to bound Tb3+. The correlation between energy transfer efficiency and ligand structure for three analogous compounds were investigated.
我们合成了三种聚醚化合物(1-3),它们的两个末端都有两个以上的荧光分子,并讨论了它们与 Tb3+ 的络合性质。与 Tb3+ 形成络合物后,由于分子内能量从香蒽发色团转移到结合的 Tb3+ 上,在可见光区域观察到尖锐的荧光线。研究了三种类似化合物的能量传递效率与配体结构之间的相关性。
