Used in organic semiconductor materials due to its extended aromatic structure and electron-rich nature. It serves as a building block in the synthesis of conjugated polymers and small molecules for organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs). Its bromine functionality allows for further cross-coupling reactions, enabling the construction of complex π-conjugated systems. Also explored in photovoltaic applications as a component in donor-acceptor type materials for organic solar cells.
