Used as a hole-transporting material in organic light-emitting diodes (OLEDs), enhancing device efficiency by facilitating the movement of positive charges. Also applied in photorefractive materials for holographic data storage due to its excellent photoconductivity and thermal stability. Commonly found in electrophotographic imaging systems as a charge transport agent. Shows potential in perovskite solar cells as a dopant-free hole-transport layer, contributing to improved device performance and longevity.
