Used as a key intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its brominated structure allows for efficient cross-coupling reactions, making it valuable in the preparation of conjugated polymers and small molecules for organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). The heptyl chain enhances solubility in organic solvents, facilitating solution-based processing in device fabrication. Commonly employed in research and development of high-performance organic electronic materials.
