Used in organic electronics, particularly as an intermediate in the synthesis of functional materials for OLEDs (organic light-emitting diodes). Its carbazole core provides good hole-transport properties and thermal stability, making it valuable in the development of emissive or host materials for blue-light emitting devices. Also employed in the preparation of photorefractive materials and dyes due to its ability to undergo functionalization at multiple sites. Its ketone group allows for further chemical modification, enabling the tuning of electronic properties in advanced optoelectronic applications.
