Abstract:Terdentate ligands L10–L14 and
their heteroleptic [L
k
Ln(hfac)3] complexes (Ln = La, Eu, Gd, Er, or Y; H-hfac = 1,1,1,5,5,5-hexafluoropentane-2,4-dione)
exhibit multifactorial correlations between the ligand’s structural
frameworks, including their level of preorganization and steric congestion
and their affinities and selectivities for catching the trivalent
lanthanide containers [Ln(hfac)3]. The polyaromatic ligand
scaffolds could be stepwise modulated via lanthanide–template
synthetic strategies, using in… Show more
