General description

2-Bromo-3-hexylthiophene is a monomeric precursor that forms bromo terminate polymers. It is synthesized by the bromination of hexylthiophene.

Application

2-Bromo-3-hexylthiophene is majorly used in the formation of π-conjugated conductive polymers (CPs) for the fabrication of organic field effect transistors (OFETs) and organic photovoltaics (OPVs). The Grignard metathesis (GRIM) polymerization of 2-Bromo-3-hexylthiophene terminates a bromine and a proton at both ends to form conductive poly(3-hexylthiophene) (P3HT).
