Red Phosphorescent Iridium(III) complexes containing Phenylquinoline-thiophene Main Ligand for Organic Light-Emitting Diodes |
| 초록 |
The synthesis, photophysics, electrochemistry and electrophosphorescent properties of novel red phosphorescent cyclometalated iridium(III) complexes, [4-phenyl-2-(thiophen-2-yl)quinoline]2 Iridium acetylacetonate (ThPhQ)2Ir(acac), [4-phenyl-2-(thiophen-2-yl)quinoline]2 Iridium picolinic acid (ThPhQ)2Ir(pic), [4-phenyl-2-(thiophen-2-yl)quinoline]2 Iridium picolinic acid N-oxide (ThPhQ)2Ir(picN-O) were synthesized. The phosphorescence organic light-emitting diodes (PhOLEDs) based on these complexes with the configuration of ITO/PEDOT:PSS (40nm)/CBP : TPD : PBD : Ir(III) complexes (70nm)/Bphen (20nm)/LiF (0.7nm)/ Al (100nm) were fabricated. The solution-processed PhOLEDs based on small molecule CBP:TPD:PBD (60:12:28) as the host and (ThPhQ)2Ir(picN-O) as the guest exhibited a maximum quantum efficiency of 6.22 % and luminance efficiency 5.97 cd/A with CIE coordinate of (0.663, 0.323). |
