Thiophene based block copolymers are synthesized by addition of bromothiophene and Knochel-Hauser base (TMPMgCl·LiCl). Nickel-catalyzed deprotonative C–H coupling polycondensation of 3-substituted-thiophenes proceeds to give head-to-tail-type poly(3-substituted thiophen-2,5-diyl) bearing nickel at the polymer end. Block copolymers of thiophene derivatives are obtained by successive addition of 2-bromo-3-alkylthiophene and magnesium amide to a living polythiophene end. The use of nickel catalyst bearing an o-tolyl group gives the tolyl-group-terminated thiophene diblock copolymers in highly efficiently. Triblock copolymer is also synthesized by the iterative addition of bromothiophene and TMPMgCl·LiCl.

High-molecular-weight head-to-tail-type regioregular polythiophenes are synthesized by [CpNiCl(SIPr)]-catalyzed dehydrobrominative polycondensation. Polycondensation of 2-bromo-3-hexylthiophene at the C–H bond proceeds with an equimolar amount of TMPMgCl·LiCl and a catalytic amount of [CpNiCl(SIPr)] to afford the regioregular poly(3-hexylthiophene) (HT-P3HT) with up to Mw = 815000. A self-standing HT-P3HT film is obtained with the regioregular HT-P3HT of Mw = 414000, while the attempted formation of the corresponding film with lower-molecular-weight HT-P3HT (Mw = 38000) is unsuccessful.
