Product Description 2-Bromo-3-hexylthiophene is a monomeric precursor that forms bromo terminate polymers. It is synthesized by the bromination of hexylthiophene. Product Application 2-Bromo-3-hexylthiophene is used in the synthesis of End-capped Regioregular Poly(3-hexylthiophene). It is also used to synthesize well-defined head-to-tail-type oligothiophenes which are used in a number of high-technology applications including OLEDs. 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).
