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, bulky structure suppresses unwanted aggregation and enhances thermal stability, making it suitable for high-performance blue OLEDs. It is also employed in organic photovoltaics and perovskite solar cells as an interfacial layer to optimize charge extraction and reduce recombination losses.
