Used as a key intermediate in organic semiconductor materials, particularly in the development of blue-emitting compounds for OLED (organic light-emitting diode) devices. Its rigid, extended aromatic structure enhances thermal stability and electron delocalization, making it suitable for optoelectronic applications. Commonly employed in the synthesis of host materials for phosphorescent OLEDs, where it helps improve device efficiency and color purity. Also explored in perovskite solar cells as a component in hole-transport materials due to its favorable energy level alignment and film-forming properties.
