Abstract:Development of new ligand systems that selectively extract and release critical elements, such as lanthanides, in the presence of other metal ions at significantly higher concentrations can provide a sustainable alternative to conventional mining and ligand-based flotation reagents. In this work, the rational design of a highly tunable molecular scaffold based on tris(2-aminoethyl)amine is elaborated. When functionalized with salicylaldehydes, the corresponding imine ligands were observed to effectively extrac… Show more
