Used as a host material in phosphorescent organic light-emitting diodes (PhOLEDs), particularly in blue-emitting devices. Its high triplet energy level makes it suitable for efficient energy transfer to blue dopants, improving device efficiency and stability. Commonly employed in the emissive layer of OLED displays and lighting panels. Also explored in thermally activated delayed fluorescence (TADF) systems due to its good charge transport properties and morphological stability.
