Abstract
The oxidative polymerization of tris(thienylphenyl)amine derivatives was performed in acetonitrile by electrochemical and chemical methods. Oligomers were synthesized by stepwise coupling using coupling reactions. The polymer prepared using the trifunctional monomer on a Pt electrode showed significantly better redox behavior compared to that of the linear polymeric analogue. The branching polymers exhibit conductivity of 2−6 S/cm, which is more than 1 order of magnitude greater than the analogous linear polymer. The electropolymerization of trifunctional monomers provides the formation of a large amount of redox active polymers with a large capacity (ca. 40 mC/cm2) and a good redox activity in the electron transfer of ferrocene on the electrode.
