Used in organic electronics, particularly in the development of organic light-emitting diodes (OLEDs), due to its excellent hole-transport properties and thermal stability. Its rigid, planar structure supports efficient π-conjugation, enhancing electroluminescence performance. Commonly employed as a dopant or host material in emissive layers to improve device efficiency and color purity. Also investigated for use in photovoltaic cells and as a building block in synthesizing advanced optoelectronic materials.
