Used as a host material in the emissive layer of organic light-emitting diodes (OLEDs), particularly in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its high triplet energy level enables efficient energy transfer to blue emitters, improving device efficiency and stability. Exhibits good thermal stability and film-forming properties, making it suitable for vacuum-deposited OLED panels used in displays and lighting. Also employed in research for tandem OLEDs and white OLEDs due to its balanced charge transport characteristics.
