Green-Emitting Symmetrical and Unsymmetrical Iridium (III) Complexes with Phosphoryl Ancillary Ligand for Highly Efficient and Stable Solution-Processed Phosphorescent Organic Light-Emitting Diodes. |
초록 |
Highly efficient green-emitting Ir(III) complexes (Ir(3-CF3BNO-N-Ethyl-Hexyl)2(dpp) and Ir(3-CF3BNO-N-Ethyl-Hexyl)2(ppp)) were synthesized and characterized. The photophysical and electrochemical properties of the complexe were investigated experimentally. Phosphorescent organic light-emitting diodes (PHOLEDs) were fabricated using the green emitters with commercial hosts and their stability was analyzed. The high performance solution-processable PHOLEDs based on Ir(3-CF3BNO-N-Ethyl-Hexyl)2(dpp) complex exhibit a maximum external quantum efficiency (EQE) of 17.23% and current efficiency (CE) of 60.08 cd A-1. The stability of the devices were studied in air without encapsulation. The symmetrical complex showed enhanced device stability compared to the unsymmetrical Ir(3-CF3BNO-N-Ethyl-Hexyl)2(ppp). |
