In this paper the electrochemical synthesis of polytriphenylamine is shown
for the first time. The electrochemical oxidation of triphenylamine (TPA) i
n nonpolar solvents leads to the formation of oligomers of TPA in solution
and the formation of a polymer film with TPA as repeating unit. Cyclic volt
ammetry of these electrochemically produced TPA films is compared to that o
f chemically produced polytriphenylamine what demonstrates a similar electr
ochemical behaviour. From FTIR spectra of the polymer film it is concluded
that the electrochemically formed polymer is more crosslinked than the chem
ically produced one. Therefore, it is a very stable redox polymer and a pro
mising candidate for application in batteries, electrochromic displays, Sen
sors or organic electronic devices. (C) 2000 Published by Elsevier Science
