While these metals are considered waste by nuclear energy manufacturers, they may serve many purposes if selectively extracted. Liquid-liquid separation of these metals can be readily achieved using carbamoylmethylphosphine oxide (CMPO) ligand derivatives dissolved in organic solvents and mixed with aqueous waste streams. While An selectivity is currently achieved by CMPO-based ligands, efficient extraction of the valuable Ln ions presents a challenge. Therefore, new ligands are being investigated in attempts to successfully target selective Ln extraction. In this study, the tripodal TREN-CMPO-OEt ligand was explored for its efficiency in Ln ion extraction. By way of ICP-AES analysis, an extraction percentage of 23.0% was determined for Tb(III), an unprecedented four to five times greater than that of any other Ln ion in the study. Further, a fluorimetric study conducted to probe the effect of solvent on luminescence showed a strong correlation between acetonitrile and increased metal-centered emissions of Tb(III) or Eu(III) ions when complexed with an uncapped CMPO-diOEt ligand.en-USLanthanideMultipodal CMPO ligandsDepartment of Chemistry, Biochemistry, and PhysicsDepartment of ChemistryResearch Subject Categories::NATURAL SCIENCESResearch Subject Categories::NATURAL SCIENCES::ChemistryArticlehttps://doi.org/10.48497/ffcq-nf17
