N,N'-Dialkyl-N,N'-diaryl-1,10-phenanthroline-2,9-dicarboxamides (IV) were predicted (DFT simulation) and then were proved experimentally to be efficient donor ligands with high and unusual selectivity for the extraction separation of lanthanides. Distribution coefficients D of lanthanide cations in two-phase aqueous solution-polar organic solvent decrease with increasing Ln(3+) atomic number. The selectivity factors SFLn1/Ln2 for adjacent lanthanide ions were found to be about 3.
N,N'-二烷基-N,N'-二芳基-1,10-菲咯啉-2,9-二甲酰胺(IV)经预测(密度泛函理论模拟),随后通过实验证明是用于镧系元素萃取分离的高效供体配体,具有高且异常的选择性。镧系阳离子在水相 - 极性有机溶剂两相体系中的分配系数D随Ln(3+)原子序数的增加而降低。发现相邻镧系离子的选择性因子SFLn1/Ln2约为3。
