Regioregularity in poly(3-alkoxythiophene)s: Effects on the Faraday rotation and polymerization mechanism

Poly(3-alkoxythiophehe)s, with different degrees of regioregularity were prepared using three different methodologies. It is shown that their Faraday rotation is highly dependent on the degree of regioregularity. The origin of the differences in regiospecificity of the methodologies is discussed.
