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

π-Electron conjugation in two dimensions.
TL;DR: Density functional theory calculations on experimentally realized 2D polymers grant insight into HOMO-LUMO gap contraction with increasing oligomer size and show fundamental differences between 1D and 2D "band gap engineering".

A Processable Green Polymeric Electrochromic
TL;DR: In this paper, the first electrochemically and chemically prepared green, soluble conducting polymer in its neutral form was reported, and the electrochemical and optical properties of this polymer were analyzed.

Polyaniline materials by emulsion polymerization pathway
TL;DR: In this article, the synthesis of PANI, substituted PANI and copolymers by the emulsion/inverted emulsion polymerization pathway is discussed, and the present status and future work of the PANI materials by emulsion polymers is brought out in this review.

TL;DR: A mechanochemically responsive nonconjugated polymer that converts to a conjugated polymer via an extensive rearrangement of the macromolecular structure in response to force is reported, based on the facile mechanochemical unzipping of polyladderene.

TL;DR: By systematically varying the acceptor strength it was possible to discriminate the two models of molecular doping, suggesting strategies for the chemical design of more efficient molecular dopants.
