Used as an electron-transporting and host material in organic light-emitting diodes (OLEDs), particularly in blue phosphorescent OLED devices. Its high triplet energy level makes it suitable for preventing energy back-transfer to the host, improving device efficiency and stability. The compound helps in balancing electron and hole injection, leading to lower driving voltages and longer operational lifetimes. It is also employed in stacked or tandem OLED structures where efficient charge transport is critical.
