monomer can be predicted by the spin-density
distribution on the aromatic ring [92]. The
introduction of electro-auxiliaries such as a silyl
group can enable dominant coupling at a
specific position [93].

5.8.2 Electrochemical Polymerization
There are several methods of electrochemical
polymerization, for example the potential
sweep, potentiostatic (constant-potential) and
galvanostatic (constant-current) methods. A
suitable method should be chosen depending
on the monomers and conditions used. Cyclic
voltammetry (CV) measurement of a monomer
in a three-electrode setup gives information on
the oxidation potential for electrochemical
polymerization. To prevent overoxidation of a
product polymer, the application of a higher
