Used as an intermediate in organic semiconductor materials, particularly in the development of hole-transport materials for OLEDs (organic light-emitting diodes). Its rigid aromatic structure enhances thermal stability and promotes efficient charge transport. Also employed in the synthesis of host materials for blue phosphorescent OLEDs due to its high triplet energy level. Shows promise in perovskite solar cells as a dopant-free hole-transport layer, improving device efficiency and stability. Additionally, utilized in research for optoelectronic devices owing to its good film-forming properties and energy level tunability.
