Used as an intermediate in organic semiconductor synthesis, particularly in the production of high-performance organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs). Its bromine functionality allows for easy cross-coupling reactions, enabling the construction of complex conjugated systems. The bulky 2-ethylhexyl groups enhance solubility in organic solvents, improving processability in thin-film device fabrication. Commonly employed in Suzuki or Buchwald–Hartwig coupling reactions to build electron-transport or emissive materials for display technologies and flexible electronics.
