Used as a hole-transporting material in organic light-emitting diodes (OLEDs), enabling efficient electron hole movement for improved device performance. Commonly employed in blue OLEDs due to its high triplet energy and good thermal stability. Also applied in organic photovoltaics and perovskite solar cells as a key component in the hole-transport layer, enhancing device efficiency and stability. Its aromatic structure supports strong film-forming properties and good charge mobility, making it suitable for use in flexible and transparent electronics.
