Used primarily as a hole-transporting material in organic light-emitting diodes (OLEDs). It helps improve device efficiency by facilitating the movement of positive charges within the emissive layer. Also employed in some organic semiconductors and photovoltaic devices due to its good thermal stability and film-forming properties. Its aromatic structure supports strong π-π stacking, enhancing charge carrier mobility. Additionally, it serves as a host material in blue-emitting OLEDs and is sometimes used in research for organic thin-film transistors.
