Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs) as a host material for blue phosphorescent emitters. Its electron-transport properties and high triplet energy make it suitable for improving device efficiency and stability. Also explored in perovskite solar cells as a hole-transporting material due to its favorable energy level alignment and film-forming characteristics. Additionally, it serves as a building block in the synthesis of more complex carbazole-based derivatives for optoelectronic applications.
