A preorganized triarmed bis-triazolylpyridine-calix(4)arene with high affinity and selectivity for minor actinides for nuclear waste treatment

The incorporation of three terdentate 2,6-bis-triazolyl-pyridine units on a calix[4]arene gives a preorganized lipophilic ligand with enhanced efficiency in binding trivalent actinides over lanthanides. Combined time-resolved laser-induced fluorescence spectroscopy, and 1D and 1H-15N HMQC NMR invest...

Description
Summary:The incorporation of three terdentate 2,6-bis-triazolyl-pyridine units on a calix[4]arene gives a preorganized lipophilic ligand with enhanced efficiency in binding trivalent actinides over lanthanides. Combined time-resolved laser-induced fluorescence spectroscopy, and 1D and 1H-15N HMQC NMR investigations allowed to propose the structures of the complexes and to provide insights into the actinide selectivity.
