Used in organic light-emitting diodes (OLEDs) as an efficient hole-transporting and emissive material due to its high thermal stability and excellent charge-transport properties. Its twisted molecular structure helps suppress aggregation and excimer formation, enhancing electroluminescence efficiency. Commonly employed in blue and green phosphorescent OLED devices for display and lighting applications. Also explored as a host material for dopants in emissive layers, improving device lifetime and energy efficiency. Suitable for use in vacuum-deposited OLED architectures owing to its good film-forming ability.
