Used in organic semiconductors, particularly in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs), due to its excellent charge carrier mobility and stability. Its fused-ring structure enhances π-π stacking, improving electronic performance in thin-film devices. Commonly employed as a building block in donor-acceptor copolymers for high-efficiency solar cells. Also explored in flexible electronics and printed circuits because of its solution-processability and compatibility with low-cost fabrication techniques.
