Synthesis and Characterization of A Dinuclear Europium Complex

摘要：

A dinuclear Eu (Ⅲ) complex Eu<,2> (DBM)<,6>TPPD (Hexa (dibenzoyl-methanido)-(N, N, N, N-tetra (2- pyridyl)-1, 4-phenylenediamine)-dieuropium (Ⅲ)) was synthesized by employing DBM (dibenzoylmethane) and TPPD (N, N, N,N-Tetra (2-pyridyl)-1, 4-phenyl- enediamine) as sensitizing ligands for the Eu (Ⅲ) ion and a bridging ligand, respectively. The analysis of the absorption, excitation, and emission spectra of the dinuclear complex along with a comparison with analogous mononuclear complex containing the same β- diketone ligands and 1, 10-phenanthroline (phen) suggests that the dinuclear complex follows the luminescence mechanism of general Ln (Ⅲ) complexes.
