Used in organic semiconductors and optoelectronic devices due to its extended aromatic structure and electron-transport properties. Commonly employed as a building block in the synthesis of conjugated polymers and small molecules for organic light-emitting diodes (OLEDs). Its bromine functionality allows for further modification via cross-coupling reactions, making it valuable in materials chemistry for tuning charge transport and emission characteristics. Also explored in photovoltaic applications as a component in donor materials for organic solar cells.
