Green to Blue-green-emitting Cationic Iridium Complexes with a CF3-Substituted Phenyl-triazole Type Cyclometalating Ligand: Synthesis, Characterization and Their Use for Efficient Light-emitting Electrochemical Cells

Green to blue-green-emitting cationic iridium complexes free of sp2 C-F bonds, namely [Ir(CF3-dPhTAZ)2(bpy)]PF6 (1), [Ir(CF3-dPhTAZ)2(dmebpy)]PF6 (2) and [Ir(CF3-dPhTAZ)2(phpyim)]PF6 (3), have been designed and synthesized with 3,4-diphenyl-5-(trifluoromethyl)-4H-1,2,4-triazole (CF3-dPhTAZ) as the cyclometalating...
