Chain-Growth Polymerization of 2‑Chlorothiophenes Promoted by Lewis Acids
Lewis acids promote the polymerization of several 2-chloroalkylenedioxythiophenes,
providing high-molecular-weight conjugated polymers. The proposed
mechanism is a cationic chain-growth polymerization, as confirmed
by end-capping reactions and a linear correlation of molecular weight
with percent conversion. The “living” character of this
process was used to prepare new block copolymers
