Conducting Polymers: Halogen Doped Polyacetylene.
TLDR
In this article, the electrical conductivity of the halogen doped transpolyacetylene system, (CH)x, was studied in terms of a model of the doping process based on charge transfer.Abstract:
A study of the electrical conductivity of the halogen doped transpolyacetylene system, (CH)x, is reported. When films of trans‐ (CH)x are exposed to chlorine, bromine, or iodine vapor, uptake of halogen occurs; and the conductivity increases markedly, over eleven orders of magnitude in the case of iodine. The behavior of the halogenated polyacetylene is like that of a series of semiconductors with activation energies which vary with halogen content. The results are discussed in terms of a model of the doping process based on charge transfer.read more

Examples of Ab Initio Calculations on Quasi-One-Dimensional Polymers
TL;DR: The application of the ab initio crystal-orbital method described in this paper is discussed in detail in Section 2.2.1. But no attempt has been made to review the numerous other applications performed by the Namur group and by other researchers, as this would increase unduly the size of this book.

New Conductivity Data on Bromine-Doped Trans-Polyacetylene
TL;DR: In this article, the authors present new experimental results on the macroscopic transport properties of bromine-doped trans-(CH)x. The mechanism of conduction which comes out of detailed analysis of the data corresponds to a model of two resistances in series, the fibrillar resistance which is typical of an amorphous semiconductor and the interfibrilar resistance (Sheng's model).
