Used in organic electronics as a building block for conjugated polymers, particularly in the development of light-emitting diodes (OLEDs) and field-effect transistors (OFETs). Its extended π-conjugated system enhances charge transport and luminescent properties. Also employed in photovoltaic cells to improve light absorption and energy conversion efficiency. Serves as a crosslinkable monomer in thin-film coatings, offering thermal stability and mechanical robustness. Applied in sensor technologies due to its fluorescence response to environmental changes.
