Used as a hole-transporting material in organic light-emitting diodes (OLEDs), enabling efficient electron hole movement for improved device performance. Also employed in organic semiconductors and photovoltaic cells due to its good thermal stability and amorphous film-forming properties. Its structural rigidity supports high glass transition temperatures, beneficial for durable thin-film layers in electronic devices. Additionally, serves as an intermediate in synthesizing more complex amine-based functional materials for optoelectronics.
