Sensing performance conjugated polymer

Because of the dimerization, the one electron density is more pronounced on the double bonds than on the single bonds this is more and more apparent when the dimerization increases. More generally, this is the case for every conjugated polymers where the one-electron density is peaked on the monomer region. In this sense, conjugated polymers are not strictly one dimensional systems but rather intermediate between quasi-zero and quasi-onedimensional systems [36, 37, 38, 39]. It seems then convenient to perform a unitary transformation which favours the orbitals localized on the monomers, in our case, on the double bonds. The new operators are then given by...

The electrogeneration of any conjugated polymer is subject to some restrictions, imposed by the need for a suitable solvent/electrolyte system in which the synthesis can be performed. As the polymerization reaction proceeds via radical cation intermediates, the process will be very sensitive to the nucleophilicity of the environment in the region near the electrode surface. In this sense, there are some limitations on the choice of the solvent and the electrolyte. In particular, the choice of the solvent is critical if side reactions, such as solvent discharge, are likely. In general, the flow of an anodic current through an electrochemical system formed by pyrrole, a solvent, and an electrolyte can initiate the following reactions ...
