Abstract: Interchain hopping of bipolarons (doubly charged defects) is discussed as a mechanism for spinless conductivity in doped polyacetylene, doped $\mathrm{poly}(p\ensuremath{-}\mathrm{p}\mathrm{h}\mathrm{e}\mathrm{n}\mathrm{y}\mathrm{l}\mathrm{e}\mathrm{n}\mathrm{e})$, and other doped polymers. It is shown that this mechanism can account for the observed dopant-concentration dependence of the conductivity in trans-polyacetylene and the observation of anomalously low magnetic susceptibilities in the highly conducting regime of several doped polymers.

TL;DR: In this paper, the in situ spectra in the visible region are presented as a function of the potential of the electrode, which can determine the level of doping of the polyaniline polymer.

TL;DR: In this paper, the crystal structure of pristine polymers was found to be composed of stacked layers constructed by a side-by-side arrangement of alkyl groups, where both the single and double layer structures were possible.

TL;DR: In this paper, the electronic structure of polyaniline acceptor-doped polyamide films has been examined by a high-resolution XPS technique and the deconvoluted core level C 1s and N 1s XPS lines show clear evidence of the existence of imine, amine and multiple charged states of N, which can be conveniently explained by assuming protonated and bipolaron states in the polymer.
