Bifunctional ZnIILnIII dinuclear complexes combining field induced SMM behavior and luminescence: enhanced NIR lanthanide emission by 9-anthracene carboxylate bridging ligands

A series of ZnIILnIII dinuclear complexes of formula [Zn(μ-L)(μ-X)Ln(NO3)2] (H2L = compartmental ligand; X = none, NO3−, OAc−, and 9-An; LnIII = Dy, Tb, Er, Nd, Yb) having double diphenoxo bridges and triple diphenoxonitrate, acetate, and 9-anthracene carboxylate bridges have been structurally and magnetically characterized, and their luminescent properties studied in the vis and NIR regions. Two DyIII complexes and two ErIII complexes combine field-induced SMM behavior and luminescent properties
