Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of conjugated polymers for organic photovoltaics (OPVs) and organic field-effect transistors (OFETs). Its structure enables strong intermolecular interactions and good charge carrier mobility, making it valuable in designing low-bandgap materials for efficient light absorption and electron transport. Also employed in the preparation of fluorescent dyes and sensors due to its rigid heterocyclic framework and tunable electronic properties.
