Used in organic electronics as a key building block for hole-transport materials in OLEDs and perovskite solar cells. Its amine functionality allows for easy modification, enabling the synthesis of derivatives with enhanced thermal stability and charge transport properties. Commonly found in dyes and fluorescent probes due to its rigid aromatic structure and ability to emit light when excited. Also employed in the development of photoconductors for imaging devices and in medicinal chemistry as a scaffold for designing bioactive compounds targeting neurological disorders and cancer.
