title = "Strong luminescent europium complexes induced by the unprecedented anti-chelate effect of acyl groups on a N6-hexadentate ligand",
abstract = "An acyl group derived-bipyridine ligand and Eu form 3:2 complexes. The structure and luminescence behaviour were evaluated, and we found an unexpected bi-nuclear complex system, which induces efficiently the luminescence of europium ion. This observation is discussed from experimental and theoretical viewpoints.",
