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 (holes) from the anode to the emissive layer. Its high glass transition temperature and good thermal stability make it suitable for use in high-performance, long-lasting OLED displays and lighting panels. Also employed in some organic photovoltaic cells and perovskite solar cells as a key component in the hole-transport layer, contributing to enhanced power conversion efficiency.
