Used as a hole-transporting material in organic light-emitting diodes (OLEDs) due to its high thermal stability and good film-forming properties. Its rigid molecular structure enhances charge carrier mobility, making it effective in improving device efficiency and lifetime. Also employed in perovskite solar cells as a key component in the hole-transport layer, contributing to higher power conversion efficiency. Commonly used in research and development of optoelectronic devices where stable and efficient hole injection is required.
