Used as an electron-transport material in organic light-emitting diodes (OLEDs), particularly in blue-emitting devices. Its rigid molecular structure and high triplet energy level make it suitable for host materials in phosphorescent OLEDs, helping to improve device efficiency and stability. Also explored in thermally activated delayed fluorescence (TADF) systems due to its ability to facilitate charge separation and energy transfer. Commonly employed in multilayer OLED architectures to enhance electron injection and reduce driving voltage.
