Used as an intermediate in organic synthesis, particularly in the development of optoelectronic materials. Commonly employed in the preparation of carbazole-based polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its rigid aromatic structure enhances thermal stability and charge transport properties in semiconductor devices. Also utilized in the synthesis of photoconductors and fluorescent dyes due to its favorable electronic characteristics.
