Preparation and Photoluminescence Properties of Bidentate Ligand Containing Electro-transporting Group and Its Europium（Ⅲ） Complex Eu（DBM）3（DPOP）
【摘要】 1,3,4-oxadiazole-contanining ligand DPOP(DPOP=2-(11-dipyrido[3,2-a:2’,3’-c]phenazine)-5-p-tolyl-1,3,4-oxadiazole) was synthesized by a convenient method and characterized by elemental analysis,IR,1H NMR. Then,corresponding Eu(Ⅲ) complex [Eu(DBM)3(DPOP)] (DBM=1,3-diphenyl-1,3-propanedionate) was prepared and characterized by elemental analysis,IR. The photophysical properties of ligand and its europium complex were investigated. The ligand emitted at 443 nm. There were different PL spectra in solid state and in solution of Eu(DBM)3(DPOP). There are two fluorescent peaks at 614 nm,400 nm in dichloromethane solution of Eu(DBM)3 (DPOP),but in solid state only red emission was observed. This result indicated that efficient energy tranfer could take place from DPOP ligand to europium ion in Eu-complex solid.
