Crystal structure and fluorescence of a europium (III) complex: EuCl3(2,2′-bipyridine N,N dioxide)·2CH3OH

We report the synthesis and characterization of a seven coordinate europium complex, [EuCl3(C10H8N2O2) AE 2CH3OH]. The growing interest in developing efficient light conversion molecular devices (LCMDs) necessitates the need for new fluorescent materials. Ideal physicochemical properties of the materials include ligand absorption, efficient metal to ligand transfer, and strong luminescence with a relatively long decay time. The design of such material requires distinct absorbing (ligand) and emitting (metal ion) components. While Eu 3+ cation has a non-degenerate emitting level, 2,2 0 -bipyridine N,N dioxide is a heterocyclic ligand known to exhibit strong lumines
