Used as a key intermediate in the synthesis of organic semiconductors and hole-transport materials for optoelectronic devices. Commonly applied in the development of organic light-emitting diodes (OLEDs) and perovskite solar cells due to its excellent thermal stability and charge-transport properties. Its molecular structure supports efficient π-conjugation and film formation, enhancing device performance and longevity. Also employed in the preparation of dyes and photoactive compounds for advanced display technologies.
