Used in organic light-emitting diodes (OLEDs) as a hole-transporting or emissive layer material due to its high thermal stability and efficient luminescent properties. Its rigid, conjugated structure enhances electron delocalization, improving device efficiency and color purity. Commonly employed in blue-emitting OLEDs for display technologies and solid-state lighting. Also explored in perovskite solar cells as a hole-transport agent to improve power conversion efficiency and device stability. Suitable for use in thin-film transistors and other optoelectronic applications requiring amorphous film uniformity and high glass transition temperatures.
