Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its structure supports charge transfer properties, making it valuable in the development of organic light-emitting diodes (OLEDs) and dye-sensitized solar cells. Also employed in the preparation of triarylamino-based dyes and fluorescent probes due to its strong electron-donating ability and thermal stability. Commonly utilized in research for designing hole-transport materials in perovskite solar cells.
