Used as a key building block in organic semiconductors, particularly in the synthesis of high-performance conjugated polymers for organic solar cells and field-effect transistors. Its rigid, planar structure enhances π-conjugation and promotes strong intermolecular interactions, improving charge carrier mobility. Also employed in the development of electrochromic materials and fluorescent probes due to its electron-deficient character and ability to form stable radical anions. Commonly used in ligand design for metal-organic frameworks and coordination chemistry where sulfur and nitrogen atoms act as donor sites.
