Uranium complexes of multidentate N-donor ligands

Lanthanide Speciation in Potential SANEX and GANEX Actinide/Lanthanide Separations Using Tetra-N-Donor Extractants

“…1,2 This interest is due to the fact that if the Ln can be separated from the SNF (Spent Nuclear Fuel) this will make the possibility of transmutation of the longlived An ions much more accessible. 3 Transmutation is the process of changing one atom into another through nuclear reactions.…”

DFT modeling of the relative affinity of nitrogen ligands for trivalent f elements: an energetic point of view

“…[6][7][8][9][10][11]. Tridentate nitrogen molecules were found to feature very good extracting properties, 7,[12][13][14][15][16] and in particular the so-called RBTP (alkylated 2,6-di(1,2,4-triazin-3-yl)pyridine) was identified as the most selective nitrogen ligand to date. 7, 15 An effort was made to determine the role of different chemical parameters like substituents, ligand concentration, solvent or number of nitrogen atoms onto the extraction efficiency.…”

Synthesis of Tri(4-tritylphenoxy)- and Hexa(4-methylphenoxy)-Substituted Hemihexaphyrazines

“…For instance, complexes of lanthanides are considered to be attractive for photodynamic therapy and virology, [1] whereas those of actinides can be recommended for analytics determination of radioactive impurities. [2] Structural peculiarities of macrocyclic core determine the capability of porphyrinoids to absorb the anions and to transport them through membranes. [3] Moreover like natural tetrapyrrolic macrocycles, porphyrinoids [4][5][6][7] show the light absorption in visible region at high level [8] what stimulates searching of new photoactive materials on their basis.…”
