Used primarily as a key intermediate in the synthesis of conjugated polymers for organic electronics. It plays an important role in the development of organic semiconductors used in organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The branched alkyl side chain enhances solubility in organic solvents, facilitating solution-processing techniques like spin coating and inkjet printing. This makes it valuable in the fabrication of flexible and large-area electronic devices. Its reactivity in cross-coupling reactions, such as Stille or Suzuki coupling, allows for efficient polymerization to build complex conjugated structures with tunable electronic properties.
