A new series of highly efficient Ir(III) complexes, (DPQ)2Ir(pic-N-O), (F4PPQ)2Ir(pic-N-O), (FPQ)2Ir(pic-N-O), and (CPQ)2Ir(pic-N-O) were synthesized for phosphorescent organic light-emitting diodes (PhOLEDs), and their photophysical, electrochemical, and electroluminescent (EL) properties were investigated. The Ir(III) complexes, including picolinic acid N-oxide (pic-N-O) ancillary ligand, are comprised
一系列新的高效Ir(III)配合物(DPQ)2 Ir(pic-NO),(F 4 PPQ)2 Ir(pic-NO),(FPQ)2 Ir(pic-NO)和(CPQ )合成了2 Ir(pic-NO)用于磷光有机发光二极管(PhOLED),并研究了它们的光物理,电化学和电致发光(EL)特性。包括吡啶甲酸N-氧化物(pic-NO)辅助配体的Ir(III)配合物包含各种主要配体,例如2,4-二苯基喹啉(DPQ),4-苯基-2-(2,3, 4,5-四氟苯基)喹啉(F 4PPQ),2-(9,9-二乙基-9H-芴-2-基)-4-苯基喹啉(FPQ)和9-乙基-3-(4-苯基喹啉-2-基)-9H-咔唑。值得注意的是,使用可溶液处理(DPQ)2 Ir(pic-NO)掺杂的CBP主体发射层制造的高性能PhOLED ,其发光效率(LE)为26.9 cd / A,相当于外部量子效率(EQE) )的14.2%。 (DPQ)2
