Specifications | MSDS | Literature and Reviews

5,5'-Dibromo-4,4'-dihexyl-2,2'-bithiophene (CAS number 214493-03-5) is a derivative of bithiophene with two hexyl groups at 4,4'-positions and two bromine group at 5,5'-positions, allowing further functionalization as well as gaining excellent solubility. It is facile for synthesising thiophene oligomer/polymer and block copolymer/small molecules with other building blocks such as perylene, triphenylamine and carbazoles.

5,5'-Dibromo-4,4'-dihexyl-2,2'-bithiophene has a well-defined structure with two thiophene units joined at 2,2'-positions and two hexyl groups being away from each other at 4,4'-positions. This is particularly useful when certain desired structure conformation to be achieved or film morphology issues to be addressed, unlike the random coupling reactions between mono-thiophenes.
