Used in organic synthesis as a key building block for conjugated polymers and small molecules in organic electronics. Its boronic acid groups enable Suzuki-Miyaura cross-coupling reactions, making it valuable for constructing π-conjugated systems. Commonly applied in the development of organic semiconductors for devices like organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). The cyclopentene and thiophene units enhance electronic properties and planarity, improving charge transport characteristics in thin-film devices.
