Key Points

This research aims to explore how variations in tripodal ligands affect their ability to extract lanthanides and their luminescence properties.
Synthesis of five tripodal ligands with varying pendant alkyl chain lengths (Et, Bu, Hex, 2-Ethyl hexyl)
Evaluation of the ligands' extraction abilities for Ln(NO3)3
Analysis of luminescence properties based on ligand structure.
Ligands showed increased extraction ability correlated with hydrophobicity variations
Luminescence intensity improved with optimal structural variations
Specific ligand configurations yielded enhanced performance in extracting lanthanides.

Abstract

Five tripodal ligands bearing carbamoylmethylphosphine oxide (CMPO) groups have been synthesized. These ligands vary in the length of the pendant alkyl chains bonded to the CMPO group (Et, Bu, Hex, 2-Ethyl hexyl), as well as the hydrophobicity of the tripodal cap (tertiary amine to methine). The effect of these structural changes on the ability of each ligand to extract Ln(NO
