Used in organic electronics, particularly in the development of high-performance organic semiconductors and polymer-based solar cells. Its rigid fused-ring structure enhances charge carrier mobility and improves the stability of electronic devices. Commonly incorporated as a building block in donor-acceptor copolymers for organic photovoltaics (OPVs), where it contributes to broad light absorption and efficient energy conversion. Also explored in thin-film transistors and light-emitting diodes due to its favorable electronic properties and planarity, which promote strong intermolecular interactions and efficient π-orbital overlap.
