Description

5,5′-Dibromo-3,3′-dihexyl-2,2′-bithiophene (CAS No. 170702-05-3) is a high-purity bithiophene derivative with the molecular formula C₂₀H₂₈Br₂S₂. This compound features a conjugated bithiophene core substituted with hexyl chains at the 3,3′-positions and bromine atoms at the 5,5′-positions, making it an excellent building block for organic semiconductors, conductive polymers, and optoelectronic materials. Its IUPAC name is 5-bromo-2-(5-bromo-3-hexylthiophen-2-yl)-3-hexylthiophene. The hexyl groups enhance solubility in organic solvents, while the bromine atoms serve as reactive sites for further functionalization via cross-coupling reactions (e.g., Suzuki or Stille couplings). This product is ideal for researchers developing organic field-effect transistors (OFETs), organic photovoltaics (OPVs), and light-emitting diodes (OLEDs). Packaged under inert conditions to ensure stability and purity.

Application

5,5′-Dibromo-3,3′-dihexyl-2,2′-bithiophene is widely used as a monomer or intermediate in the synthesis of conjugated polymers for organic electronics. Its brominated thiophene units enable polymerization via metal-catalyzed cross-coupling, yielding materials with tunable bandgaps for photovoltaic applications. The hexyl side chains improve processability without significantly compromising charge transport properties. Researchers also employ this compound in small-molecule semiconductors for OFETs due to its ability to form ordered thin films. Its versatility makes it valuable for exploring structure-property relationships in π-conjugated systems.
