Poly(p-phenyleneamineimine): Synthesis and Comparison to Polyaniline

Article abstract of DOI:10.1021/ja00246a026

We present a complete account of results on the preparation of a polymer which could only be a poly(p-phenyleneamineimine) (PPAI) and which, by several criteria, has the same properties of polyaniline (PANI).We also present detailed results of comparative studies of not only PANI with PPAI but of PANI with phenyl-capped octaaniline (COA), a discrete length, fully characterized molecule.Finally, we present support for the hypothesis that acid doping of PANI involves the proton induced spin unpairing mechanism for protonated quinoneimine moieties.We conclude that magnetic and transport data are qualitatively consistent with that of a Fermi"glass" model and not with that of a metal.
