Used in organic semiconductor materials due to its conjugated structure, enabling applications in organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). Serves as a building block in the synthesis of conjugated polymers and small molecules for optoelectronic devices. Common intermediate in cross-coupling reactions, such as Suzuki or Stille couplings, to form extended π-conjugated systems for use in photovoltaic cells and sensors. Its bromine functionality allows for easy functionalization and incorporation into larger aromatic frameworks.
