Used as a sulfur-containing conjugated organic intermediate in the synthesis of organic semiconductor materials, conjugated polymers, organic field-effect transistors (OFETs), organic photovoltaic (OPV) materials, and other optoelectronic functional molecules. The alkyl-substituted terthiophene structure provides improved solubility and processability for polymer and material synthesis.
