Benzo[4,5]thieno[2,3-b]pyridine (BTP) was newly developed as an electron deficient moiety for high triplet energy materials and two BTP derivatives with the BTP and carbazole groups were synthesized as high triplet energy bipolar host materials. The BTP derivatives were effective as the host materials for green and blue phosphorescent organic light-emitting diodes and a high quantum efficiency above 20% was achieved both in green and blue devices.
苯并[4,5]噻吩并[2,3-b]吡啶(BTP)是新开发的作为电子缺电子部分的高三重态能量材料,两种带有 BTP 和咔唑基团的 BTP 衍生物被合成作为高三重态能量双极主体材料。BTP 衍生物可有效作为绿色和蓝色磷光有机发光二极管的主体材料,在绿色和蓝色器件中均实现了超过 20%的高光量子效率。
