TLDR
When silvery films of the semiconducting polymer, trans polyacetylene, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.Abstract:
When silvery films of the semiconducting polymer, trans‘polyacetylene’, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give, depending on the extent of halogenation, silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.read more

Slow Doping Rate in DNA−Poly(o-methoxyaniline) Hybrid: Uncoiling of Poly(o-methoxyaniline) Chain on DNA Template
Arnab Dawn,Arun K. Nandi +1 more
TL;DR: In this paper, the doping rate of biomolecular hybrids of the deoxyribonucleic acid−poly(o-methoxyaniline) (DNA−POMA) system has been measured by UV−vis spectroscopy and pH study for the three different compositions (WDNA = 0.21, 0.45, and 0.71, WDNA = weight fraction of DNA) of the blend.

Electrochemical and electrochromic response of poly(thiophene-3-acetic acid) films
M. Giglioti,Francisco Trivinho-Strixino,J.T. Matsushima,Luis O.S. Bulhões,Ernesto C. Pereira +4 more
TL;DR: In this article, Thiophene-3-acetic acid has been polymerized in chloroform by a chemical method using FeCl 3 as oxidant, and the films were prepared casting the solubilized polymer on ITO electrodes and studied using cyclic voltammetry, chronoamperometry and spectroelectrochemistry.

Structural and electrochemical characterisation of [Pd(salen)]-type conducting polymer films
João Fonseca,João Tedim,Krzysztof Biernacki,Alexandre L. Magalhães,S J Gurman,Cristina Freire,A.R. Hillman +6 more
TL;DR: In this paper, the oxidative polymerization of four structurally-related [Pd(salen)] complexes and characterisation of the resulting polymeric films by cyclic voltammetry (CV), UV-visible transmission spectroscopy, X-ray absorption spectrograms, and Xray photoelectron spectrographs is reported.
