Used as a hole-transporting material in organic light-emitting diodes (OLEDs), this compound helps improve device efficiency and stability by facilitating the movement of positive charges. Its rigid molecular structure supports high glass transition temperatures, enhancing thermal stability in thin-film layers. Commonly employed in blue OLEDs, it contributes to lower driving voltages and longer operational lifetimes. Also utilized in perovskite solar cells as a dopant-free hole-transport layer, enabling scalable and stable photovoltaic performance.
