An electron‐transporting host material suitable for deep‐blue phosphorescent organic light‐emitting diodes has been developed. The material exhibits electron‐transport characteristics, high triplet energy, and high thermal stability. It is designed by integrating electron‐transporting pyridoindole substituents into a bulky adamantane core (see Figure), and is demonstrated to be an excellent host for
已经开发出适用于深蓝色磷光有机发光二极管的电子传输基质材料。该材料具有电子传输特性,高三重态能量和高热稳定性。它是通过将电子传输的吡啶并吲哚取代基整合到庞大的金刚烷核中而设计的(参见图),并被证明是深蓝色磷光掺杂剂发射体的绝佳宿主。
