Abstract

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 Ln3+ atomic number. The selectivity factors SFLn1/Ln2 for adjacent lanthanide ions were found to be about 3.
