Abstrakt: A novel "Ring-expansion" strategy is proposed to optimize traditional host molecular structures, featuring a rigid molecular skeleton and excellent transport of carriers. Consequently, the two novel host materials facilitate the fabrication of efficient phosphorescent OLEDs with suppressed efficiency roll-off compared to OLEDs based on the conventional host material (mCP).
