Used in organic electronics as a building block for conjugated polymers in high-performance organic solar cells and field-effect transistors. Its electron-deficient structure enhances charge transport properties and improves device efficiency. Commonly employed in donor-acceptor copolymers to tune bandgap and energy levels for better light absorption and charge separation. Also explored in photodetectors and near-infrared emitting devices due to its strong intermolecular interactions and thermal stability.
