Used in organic electronics as a key building block for conjugated polymers and small molecules in organic solar cells and field-effect transistors. Its electron-deficient nature enhances charge transport properties, making it valuable in designing donor-acceptor type materials. Also employed in fluorescent probes and sensors due to its strong emission and ability to interact with biological molecules. Commonly used in Suzuki and Knoevenagel coupling reactions to extend π-conjugation for optoelectronic applications.
