Used as a high-performance hole-transporting material in organic light-emitting diodes (OLEDs) and perovskite solar cells due to its excellent thermal stability and efficient charge transport properties. Its extended aromatic structure enhances hole mobility, improving device efficiency and longevity. Also employed in multilayer organic electronics where energy level alignment and film-forming characteristics are critical. Shows promise in optoelectronic devices requiring stable amine-based semiconductors.
