Key Points

This research aims to understand how alkyl substituents influence the ability of bis-lactam-1,10-phenanthroline ligands to extract lanthanides.
Synthesis of various alkyl-substituted bis-lactam-1,10-phenanthroline ligands.
Evaluation of ligand's extraction efficiency for light lanthanides.
Analysis of coordination selectivity using size-specific cavities.
Different alkyl chains showed varying effectiveness in extracting light lanthanides.
Optimal alkyl chain length improved selectivity and extraction rates.
Enhanced extraction linked to specific interactions within the coordination cavities.

Implication

Experiment examines how alkyl chains affect lanthanide extraction by specific ligands, suggesting optimization strategies.

Abstract

2,9-Diamide-1,10-phenanthroline (DAPhen) and bis-lactam-1,10-phenanthroline (BLPhen) ligands have been demonstrated to extract light lanthanides through size-specific coordination cavities selectively. Given that the alkyl chain has a substantial impact on the extraction...
