Used as an organic semiconductor in optoelectronic devices, particularly in organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid, conjugated structure enables efficient charge transport and good thermal stability, making it suitable as a host or emissive material in blue-emitting OLEDs. Also employed in perovskite solar cells as a hole-transporting material due to its favorable energy levels and film-forming properties. Its pyrazole groups enhance electron-donating ability and improve device efficiency.
