Used as a hole-transporting material in organic light-emitting diodes (OLEDs) due to its high thermal stability and good film-forming properties. Its molecular structure supports efficient charge transport, making it suitable for use in blue-emitting OLED devices. Also employed in perovskite solar cells as a key component in the hole-transport layer, enhancing device efficiency and stability. Commonly doped with lithium salts or other additives to improve conductivity in device applications.
