Used as a hole-transporting material in organic light-emitting diodes (OLEDs) due to its excellent thermal stability and high triplet energy level. It enhances device efficiency by facilitating balanced charge injection and transport. Also applied in perovskite solar cells as a dopant-free hole-transport layer, improving device stability and reducing fabrication costs. Its amorphous nature allows for uniform thin-film formation, making it suitable for use in thin-film transistors and other organic electronic devices.
