Used primarily in organic light-emitting diodes (OLEDs) as a host material in blue-emitting layers due to its high triplet energy and good thermal stability. Its rigid molecular structure supports efficient energy transfer and helps prevent exciton quenching. Also employed in phosphorescent OLEDs (PhOLEDs) to enhance device efficiency and lifespan. Commonly found in display technologies and solid-state lighting applications. Its hole-transport properties make it suitable for use in multilayered device architectures, particularly in hole-transport layers.
