Used 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 molecular structure supports efficient energy transfer and helps prevent exciton quenching, improving device efficiency and lifespan. Also employed in phosphorescent OLEDs (PhOLEDs) for display and lighting technologies. Shows promise in thermally activated delayed fluorescence (TADF) systems when paired with appropriate emitters. Commonly found in multilayer thin-film architectures where charge transport and energy alignment are critical.
