Used as a highly efficient hole-transporting material in organic light-emitting diodes (OLEDs) and perovskite solar cells due to its excellent thermal stability and extended π-conjugated structure. Its branched multi-amine design enhances charge carrier mobility and film-forming properties, making it ideal for use in high-performance optoelectronic devices. Also employed in organic thin-film transistors and as a host matrix in emissive layers to improve device efficiency and longevity.
