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 <sup>1</sup>H-<sup>15</sup>N HMQC NMR investigations allowed to propose the structures of the complexes and to provide insights into the actinide selectivity.
