Used in organic electronics as a building block for conjugated polymers and small molecules in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its rigid, planar structure enhances π-electron delocalization, improving charge carrier mobility. Also employed in the synthesis of semiconducting materials and luminescent compounds for optoelectronic devices. Common in research for developing sensors and electroactive coatings due to its redox activity and stability.
