Our deep‐red phosphorescent organic light‐emitting diode (OLED) demonstrated a long lifetime at 85°C. This durability was derived not only from a stable exciplex host but also from a dopant with high thermal resistivity. The exciplex host made by a premix technique also worked as well as that made by co‐deposition.
