Strong Luminescent Europium Complexes Induced by the Unprecedented Anti-chelate Effect of Acyl Groups on a N-6-Hexadentate Ligand
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.
