The molecule consists of two thiophene rings joined directly to each other to form a bithiophene unit, with bromine atoms attached at both terminal ends of the ring system. The bithiophene unit itself is one of the most important cores in organic semiconductors because it provides a delocalised pi-electron system. The presence of two bromine atoms at the terminal positions makes this compound a difunctional monomer, ready to enter a wide range of cross-coupling reactions that extend the conjugation length of the resulting chain.\u003c\/p\u003e\n\u003cp\u003eThe reason this material is selected is its symmetry and its reactivity, both of which are very well suited to controlled polymerisation. The carbon–bromine bonds at the alpha positions of the thiophene rings are readily activated by palladium as well as nickel catalysts, so this monomer can be reacted through Suzuki, Stille or Kumada coupling, or through direct arylation, to produce conjugated polymers with a regular and well-defined structure. The electron-donating character of the thiophene rings helps to lower the band gap of the resulting material, while the difunctional substitution pattern makes it possible to build alternating polymers in which donor and acceptor units follow one another along the backbone.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, this building block is typically used in university and institutional research groups working on organic electronics and conjugated polymer synthesis.
