Used as a high-performance hole-transporting material in organic light-emitting diodes (OLEDs), enabling efficient electron blocking and enhancing device efficiency. Its rigid, bulky structure improves thermal stability and prevents crystallization in thin films, making it ideal for stable blue OLEDs. Also employed in perovskite solar cells to facilitate hole extraction and improve power conversion efficiency. Suitable for use in transparent and flexible electronic devices due to its excellent film-forming properties and morphological stability.
