Our developed hole‐transport materials (HTMs) with deep HOMO levels improve a lifetime of a deep‐blue OLED in 85°C operation. Furthermore, a deep‐blue OLED with these HTMs achieved an LT 95 of 360 h in room temperature operation (50 mA/cm 2 ). These HTMs are also applicable for red and green devices.
