  A series of CBP-derivatives as host materials for blue phosphorescent organic light-emitting diodes

  摘要：

  我们报道了一系列具有优越热学和电子特性的CBP衍生物，作为蓝色电致磷光有机发光二极管的宿主材料。我们系统地改变了联苯单元在2位和2′位，以及咔唑基团在3位和6位的取代模式。与结晶母体化合物CBP相比，所有甲基和三氟甲基取代的衍生物均表现出非晶态行为。在联苯的2位和2′位的取代导致了苯环的扭曲。因此，分子的共轭程度受到限制，这导致其激发态能量增大，约为2.95 eV，而CBP为2.58 eV。在活性3位和6位的咔唑基团上进行甲基取代使得材料对氧化具有电化学稳定性。
