Used in organic light-emitting diodes (OLEDs) as a hole-transporting material due to its high thermal stability and efficient charge transport properties. Its rigid molecular structure helps prevent crystallization in thin films, making it suitable for stable blue-emitting OLED devices. Also employed as a host material in phosphorescent OLEDs, where it supports high electroluminescence efficiency. Additionally, utilized in organic photovoltaics to enhance the efficiency of converting light energy to electricity and improve device lifetime. Commonly found in display technologies and advanced lighting systems.
