Used as a key intermediate in the synthesis of organic semiconductors, particularly in the production of conjugated polymers and small molecules for optoelectronic devices. Commonly applied in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs) due to its strong electron-donating properties and good charge transport characteristics. Its structural features enhance π-conjugation and improve film morphology in thin-film transistor applications. Also employed in dye-sensitized solar cells and as a building block for push-pull chromophores in nonlinear optical materials.
