Abstract

New tripodal 1,2,3-triazole ligands based on triphenylphosphine oxide platform with different linker lengths have been synthesized, and their structure has been determined by elemental analysis, 1H, 13C, and 31P NMR spectroscopy, mass spectrometry, and vibrational (IR and Raman) spectroscopy. The coordination and extraction properties of the new ligands have been studied in the complexation with uranyl nitrate and extraction of micro amounts of uranium(VI) from aqueous phase to 1,2-dichloroethane.
