Used as a high-performance host material in blue phosphorescent organic light-emitting diodes (OLEDs). Its strong triplet energy and good thermal stability make it ideal for efficient blue emission in display and lighting technologies. Commonly employed in multilayer OLED devices to improve electron transport and prevent exciton quenching. Also utilized in research for developing stable, long-life electroluminescent devices due to its excellent morphological stability and wide energy bandgap.
