“…The highest extraction performance is comparable to that reported by Scott and co-workers for tripodal diglycolamides constructed upon the trityl platform. 13,14 In general, the C-pivot diglycolamides 3a-d show a pronounced relative extraction ability toward Eu 3+ extracting it up to five times more efficient than Am 3+ (3b). The trialkylbenzene platform derived ligands 5a,b, using the preorganization concept proposed by Anslyn and co-workers, 19 extract better than 3a, however, not as well as the N-substituted ligands 3b-d.…”

“…10 They act as tridentate binding groups 11 thanks to the presence of an additional oxygen atom between the carbonyl groups and therefore display a very high affinity toward actinides and lanthanides 12 compared to other diamides. Except for the work of Scott and co-workers 13,14 related to the trityl platform, to the best of our knowledge there are no reports on preorganized diglycolamides containing more than one ligating group in a single ionophore.…”

“…Use of iso-decanol as phase modifier along with CMPO has also been reported recently [24,25]. Nowadays, use of ligands, where known functionality is attached to supra molecular frame work, have been observed in the literature to enhance the efficiency and selectivity of separation [26][27][28][29][30]. Due to the large hydrophobicity of the metal complex (coordinated with the supramolecular ligands), probability of third phase formation also decreases.…”

“…As a result, attempts have been made to functionalize these ligands on a rigid platform such as calix [4]arenes or on a tripodal platform. [5][6][7][8][9][10][11] In all cases, significant enhancements in the extraction ability of the ligands have been observed.…”
