Used primarily as an intermediate in organic synthesis, especially in the preparation of liquid crystals and conjugated polymers for electronic applications. It serves as a building block in the formation of more complex aromatic compounds due to the reactive bromine atom, which enables cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in the development of organic semiconductors, field-effect transistors (OFETs), and photovoltaic materials. Also utilized in the synthesis of side-chain functionalized materials for optoelectronic devices. Its long alkyl chain enhances solubility in organic solvents, facilitating processing in thin-film device fabrication.
