Experimental and computational studies of the binding properties of lower rim tetra- and di-substituted calix[4]arene amide derivatives with metal ions

Mixed-ligand lanthanide complexes supported by ditopic bis(imino-methyl)-phenol/calix[4]arene macrocycles: synthesis, structures, and luminescence properties of [Ln2(L2)(MeOH)2] (Ln = La, Eu, Tb, Yb)

“…Few studies have reported solution thermodynamic data for f-element calixarene complexes. [64][65][66][67][68][69] We have investigated the Ln 3+ binding ability of the related salicylaldimine functionalized calix [4]arene ligand (L 1 ) 4− in MeOH. The log K 11 value for this complex of 6.0 compares well with that determined for the present complexes.…”
