Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting layers for OLED (organic light-emitting diode) devices. Its rigid, planar structure enhances thermal stability and improves charge transport properties, making it suitable for high-performance displays and lighting applications. Commonly employed in host materials for phosphorescent OLEDs due to its high triplet energy level, which helps prevent energy back-transfer and improves device efficiency. Also explored in perovskite solar cells as a hole-transporting material owing to its favorable energy level alignment and film-forming properties.
