Coordination-Driven Nanosized Lanthanide “Molecular Lantern” with Tunable Luminescent Properties

A new family of nanosized lanthanide “molecular lanterns” Ln III 2 L 4 (Ln(III) = La ( 1 ), Ce ( 2 ), Sm ( 3 ), Eu ( 4 ) and Tb ( 5 )) with tunable luminescent properties based on the bent 3,5-bis(3-benzocarboxylate)-4-amino-1,2,4-trizole ligand and nine-coordinated square antiprism Ln(III) node was reported.
