introducing versatile functionalities into
polymers. This electrochemical polymer
reaction is a kind of post-polymerization
functionalization (or simply
post-functionalization) (
Figure 6.36
) [121]. The
reaction ratio (or the degree of
functionalization) of the repeating reaction sites
influences various properties of the resulting
conducting polymer, including its absorption,
photoluminescence and electrochemistry. As
anodic reactions, oxidative halogenations,
cyanations and pyridinations of conducting
polymers are known to proceed when using the
corresponding nucleophilic dopants. Cathodic
reaction such as reductive hydrogenation of the
9-fluorenone moiety in a conducting polymer is
also possible, so that paired electrochemical
polymer reactions in a single cell can be
designed and give good current efficiency.

The main advantage of electro-organic
synthesis is the ability to rapidly switch the
application of electrical potential to the working
electrode either on or off. By applying this
