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

Reversible iodine absorption of nonporous coordination polymer Cu(TCNQ)
TL;DR: In this article, a semiconductor-based iodide-containing salt of Cu(TCNQ) was reported, where the copper ion is coordinated with an iodide anion and neutral TCNQ. The salt is a compound semiconductor (σRT = 3 × 10−3 S cm−1, compaction pellet).

13C NMR and Fourier transform infrared study of electrochemically prepared polythienylene film
TL;DR: In this article, the 13 C NMR and Fourier transform infrared (FTIR) spectra of an electrochemically prepared polythienylene film have been obtained, showing that poly(2,5-thienyl)-polysilane exhibits only two sharp absorption bands, at 124.8 and 136.5 ppm downfield from TMS.

The electronic properties of [CH(FeCl4)0.061]x
TL;DR: In this article, the temperature dependence of electron paramagnetic resonance (EPR) results on [CH(FeCl 4 ) 0.061 ] x are reported, indicating metallic charge transport along the polyacetylene chain interrupted by the interfibril contact resistances and also dragged primarily by the dopant ions.
