Used as an electron-deficient building block in organic semiconductors, particularly in the synthesis of conjugated polymers and small molecules for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its strong electron-accepting nature enhances charge separation and electron transport in active layers of solar cells. The hexyloxy side chains improve solubility in organic solvents, facilitating solution processing for thin-film device fabrication. Also explored in fluorescent probes and sensors due to its distinct optoelectronic properties.
