Used primarily in organic light-emitting diodes (OLEDs) as a hole-transporting material due to its excellent thermal stability and efficient charge transport properties. Its extended aromatic structure enhances electron delocalization, improving device efficiency and brightness in display and lighting technologies. Also employed as a dopant or host material in emissive layers to optimize energy transfer and color purity. Suitable for use in vapor-deposited small-molecule OLEDs in high-performance electronic devices.
