Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of thermally activated delayed fluorescence (TADF) materials for OLED displays and lighting. Its rigid, conjugated structure enhances electron transport and promotes efficient reverse intersystem crossing, improving device efficiency. Also employed in the preparation of hole-transport materials and emissive layer dopants in advanced optoelectronic devices. Shows promise in perovskite solar cells as a component of stable, high-performance hole-transport layers.
