Used as a key intermediate in the synthesis of conjugated polymers for organic electronic devices. Its structure enables efficient π-conjugation, making it valuable in the development of organic semiconductors, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The compound’s fused ring system with electron-rich moieties enhances charge transport properties when incorporated into polymer backbones. It is also explored in the design of donor-acceptor type copolymers to tune bandgap and improve device efficiency.
