Abstract

Conductive polymers and a method of forming conductive polymers. More particularly, a method of forming head-to-tail coupled regioregular poly-(3-substituted) thiophenes having improved charge carrier mobility and current modulation. Also, monomers having two different halogen leaving groups and which form regioregular poly-(3-substituted) thiophenes more efficiently and economically than other processes. Polythiophene polymers, films and articles are also provided.
