Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of high-performance OLED (organic light-emitting diode) materials. Its rigid, extended π-conjugated structure enhances electron transport and thermal stability in thin-film devices. Commonly employed in the fabrication of blue-emitting layers due to its favorable energy levels and resistance to crystallization. Also explored in perovskite solar cells as a hole-transporting material owing to its good film-forming properties and compatibility with various dopants.
