摘要：

A novel asymmetric disubstituted polybithiophene was found to display well-defined redox processes which are correlated to the consecutive formation of radical cations, dimerized radical cations, and dications. A mixed-valence electrical transport was observed together with a 10-fold increase of the conductivity with the apparition of dimerized polarons and bipolarons.
