Widely used in organic light-emitting diodes (OLEDs), especially as a host material in blue phosphorescent and thermally activated delayed fluorescence (TADF) devices. Its high triplet energy level makes it suitable for efficient energy transfer to blue emitters, helping achieve high luminous efficiency and color purity. The compound exhibits excellent thermal stability and morphological stability, which contributes to longer device lifetime. It is also employed in multilayer OLED structures due to its good film-forming properties and compatibility with vacuum deposition processes. Additionally, its electron-transport characteristics support balanced charge injection when paired with appropriate electron-transport layers.
