Used in organic electronics, particularly as a building block in the synthesis of conjugated polymers for high-performance organic solar cells. Its structure supports strong intermolecular interactions and good charge carrier mobility, making it valuable in donor materials for polymer-based photovoltaics. Also employed in field-effect transistors (OFETs) due to its semiconducting properties and compatibility with solution-processing techniques. The presence of long octyl chains enhances solubility in organic solvents, facilitating thin-film fabrication.
