A Simple Method to Prepare Head-to-Tail Coupled, Regioregular Poly(3-alkylthiophenes) Using Grignard Metathesis

Poly(3-alkylthiophenes) (PATs) exhibit promising electronic properties; however, their regioregular syntheses are only beginning to be developed. The authors describe a new method for the preparation of head-to-tail coupled (HT) PATs, in which methylmagnesium bromide is utilized to
