2,2′-Bithiophene, 5,5′-dibromo-3,3′-bis[2-[2-(2-methoxyethoxy)ethoxy]ethoxy]-（Cat No.:L002947）is a highly functionalized bithiophene derivative featuring bromine atoms at the 5 and 5′ positions and extended oligoethylene glycol chains at the 3 and 3′ positions. The dibromo groups enable cross-coupling reactions, such as Suzuki or Stille, for constructing conjugated polymers and organic semiconductors. The oligoether side chains improve solubility in polar solvents and enhance processability in solution-phase synthesis. This compound is commonly used in the design of flexible, high-performance materials for organic electronics, including OFETs, OPVs, and electrochromic devices, due to its tunable electronic properties and structural versatility.
