Used in organic light-emitting diodes (OLEDs) as a hole-transporting material due to its high thermal stability and excellent film-forming properties. Its rigid molecular structure helps prevent aggregation and excimer formation, making it effective in blue-emitting OLED devices. Also employed as a host material in phosphorescent OLEDs, where it supports efficient energy transfer to emissive dopants. Commonly found in display technologies and solid-state lighting applications.
