Used as a key building block in organic semiconductors, particularly in the synthesis of high-performance conjugated polymers for organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances π-π stacking, improving charge carrier mobility. Also employed in the development of donor-acceptor type polymers to tune bandgap and optimize light absorption in solar cells. Shows promise in printable electronics due to good solution processability and thermal stability.
