Highly quantum efficiency trinuclear Eu3+ complex based on tris-diketonate ligand

Synthesis and spectroscopic behavior of highly luminescent trinuclear europium complexes with tris-β-diketone ligand

“…The trinuclear europium complexes C1-C3 were prepared by enolization of the tris-b-diketone and dibenzoylmethane ligands in the presence of sodium ethoxide at first, and then complexation using Bipy or Phen as the third ligand with europium chloride in ethanol solution according to the method of Ref. [11].…”

“…Generally, one efficient method of improving the luminescent properties is the introduction of organic ligands with multiple binding sites in europium complexes [11]. Therefore, to further develop the luminescent properties of europium complexes, we designed and synthesized a new tris-b-diketone ligand, 2-[4, 6-bis-(1-benzoyl-2-oxo-2-phenyl-ethyl)- [1,3,5]triazin-2-yl]-1,3-diphenyl-propane-1,3-dione (H 3 L).…”

“…This is a consequence of the high absorption of the beta-diketonate species and its efficient energy transfer [20][21][22].…”
