Poly electropolymerization with alternate

Solvent retention within the polymer matrix, as discussed in Chapter 3 for P(ANi), or alternatively, retention of solvent "affinity sites", are important factors sometimes ignored by many workers. Thus, for instance, several poly (diphenyl amine) derivatives, when electropolymerized in acetonitrile or PC, will electrochemically cycle well only in the solvent of electropolymerization [36, 74, 67, 75]. Solvents may also be too nucleophilic besides its high solvation capability for even doped CPs, dimethyl formamide (DMF) is also a poor electropolymerization solvent due to high nucleophilicity if this is reduced with addition of protic solvents, electropolymerizations are observed [43]. Table 5-2 cited above has [43] summarized electropolymerization data for P(Py) in various solvents.
