Used in organic electronics as a building block for conjugated polymers and small molecules in organic photovoltaics (OPVs) and organic light-emitting diodes (OLEDs). Its rigid aromatic structure and electron-deficient nature enhance charge transport properties and improve device efficiency. Commonly employed in donor-acceptor copolymers to tune bandgap and energy levels for better light absorption and electron mobility. Also explored in fluorescent probes and sensors due to its luminescent characteristics in solid and solution states.
