摘要
Highly electron deficient pyrido[3',2':4,5] furo[2,3-b]pyridine (PFP) was developed as a core structure of a triplet host material and a derivative of PFP, 3-(3-(carbazole-9-yl) phenyl) pyrido[3',2':4,5] furo[2,3-b] pyridine (CzPFP), was synthesized as a bipolar host material. The CzPFP host material showed similar hole and electron densities in single charge devices, and a high quantum efficiency of 27.7% and a high power efficiency of 86.8 lm W-1 in green phosphorescent organic light-emitting diodes.
