Used as a key intermediate in organic semiconductor materials, particularly in the development of high-performance OLEDs (organic light-emitting diodes). Its rigid, conjugated structure enhances charge transport properties, making it suitable for use in blue-emitting layers. Also employed in perovskite solar cells as a hole-transporting material due to its excellent thermal stability and energy level alignment. Commonly found in research on optoelectronic devices and thin-film transistors.
