We have investigated the effect of exciplex forming host structure on organic light‐emitting diodes (OLEDs). The exciplex formation was observed by mixing two organic materials with hole transporting and electron transporting properties. The device with exciplex forming host structure exhibited improved carrier injection property and charge balance, leading to higher power efficiency and longer lifetime.
