Highly Efficient Green Emitting Heteroleptic Iridium(III) Complexes with Multifunctional Ancillary Ligands for Solution-Processed Phosphorescent Organic Light-Emitting Diodes |
| 초록 |
Two new highly efficient green-emitting heteroleptic phosphorescent iridium(III) complexes as (3-CF3BNO-EH)2Ir(OXD) and (3-CF3BNO-EH)2Ir(mCP) based on amide bridged trifluoromethyl (-CF3) substituted phenyl pyridine unit as the main ligand and 2-phenyl-5-p-tolyl-1,3,4- oxadiazole (OXD) and 9,9′-(5-methyl-1,3-phenylene)bis(9Hcarbazole) (mCP) as ancillary ligands were designed and successfully synthesized. The photophysical and electrochemical properties of the complexes were investigated experimentally as well as theoretically by using density functional theory. The high performance solution-processed PHOLEDs based on (3-CF3BNO-EH)2Ir(OXD) complex exhibit a maximum external quantum efficiency (EQE) of 19.60%, current efficiency (CE) of 59.61 cd A-1 whereas, (3-CF3BNO-EH)2Ir(mCP) showed a maximum EQE of 18.46%, CE of 58.14 cd A-1 and maximum brightness of 23375, 28804 cd m−2 respectively. |
