The series of new red emitting phosphorescent iridium(Ⅲ) complexes, (MN-TFP)2Ir(tmd), (MN-TFP)2Ir(dpd), (MN-MQ)2Ir(tmd), (MN-MQ)2Ir(dpd), (MN-Q)2Ir(tmd), (MN-Q)2Ir(dpd) based on main ligands (electron-donor group: 1-methylnaphthalene (MN) and electron-acceptor group: 4-(trifluoromethyl)pyridine (TFP), 4-methylquinoline (MQ), quinoline (Q)) and ancillary ligand(2,2,6,6-tetramethylheptane-3,5-dione (tmd), 1,3-diphenylpropane-1,3-dione (dpd)) were synthesized for phosphorescent organic light-emitting diodes (PhOLEDs). The main Ligands were synthesized by Suzuki coupling reaction and the complexes (red dopant) were synthesized by Nonoyama reaction. The OLEDs devices with the structure of indium tin oxide (ITO)/PEDOT:PSS (40 nm)/HTL (17 nm)/RH-35:red dopant (5%, 40 nm)/HCL (5 nm)/ SNABH 205: 6s-12 (5%, 15 nm)/TPBi (20 nm)/LiF (1 nm)/Al (100 nm) were manufactured. The Iridium(Ⅲ) complexes will be used as a solution process dopant for the hybrid OLED devices. |
