Used in organic electronics as a building block for high-performance semiconducting polymers in organic field-effect transistors (OFETs). Commonly incorporated into conjugated polymers for flexible electronics and thin-film transistors due to its strong intermolecular stacking and excellent charge carrier mobility. Also applied in the development of organic photovoltaics (OPVs) and perovskite solar cells as a component in hole-transport materials. Its rigid, planar structure enhances thermal stability and electronic coupling in polymer backbones, making it valuable in designing efficient, solution-processable electronic materials.
