摘要：
Three new cationic iridium(III) complexes, namely [Ir(OXD)(2)(bpy)](+)(PF6-), [Ir(OXD)(2)(phen)](+)(PF6-), [(Ir (OXD)(2)(dpq)](+)(PF6-) by utilizing the electron deficient 2,5- diphenyl-1,3,4-oxadiazole ligand with variety of electron rich ancillary ligands. Their photophysical, electrochemical and density functional theory (DFT) has been investigated. In addition, complex 2 was characterized by single X-ray diffraction while complex 1 and 3 was unsuccessful to crystalize. DFT shows that the electronic state for the complex 2 has the characteristic mixed (MLCT)-M-3 (Ir -> the ancillary ligand) and (LLCT)-L-3 (the cyclometallated ligands -> the ancillary ligand) structure.
