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.
高电子缺吡啶并[3',2':4,5]呋喃并[2,3-b]吡啶（PFP）被开发为三重态主体材料的核心结构，并且 PFP 的衍生物 3-(3-(咔唑-9-基)苯基)吡啶并[3',2':4,5]呋喃并[2,3-b]吡啶（CzPFP）被合成作为双极主体材料。CzPFP 主体材料在单电荷器件中表现出相似的空穴和电子密度，并且在绿色磷光有机发光二极管中具有 27.7%的高光量子效率和 86.8 lm W(-1)的高光功率效率。
