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

Dual dynamics of promises, and waiting games around emerging nanotechnologies
TL;DR: It is shown how the occurrence of waiting games is linked to dual dynamics of promises in two fields where nanotechnology offers an open-ended (‘umbrella’) promise: organic and large area electronics and nano-enabled drug delivery.

Iodine-doped-poly(3,4-ethylenedioxythiophene)-modified Si nanowire 1D core-shell arrays as an efficient photocatalyst for solar hydrogen generation.
TL;DR: A new 1D core-shell strategy is demonstrated for a hydrogen-generation photo-electrochemical cell (PEC) and the PEC model proposed shows a potentially promising structure for H(2) production using solar energy.

Controlled Crystallization of Conjugated Polymer Films from Solution and Solvent Vapor for Polymer Electronics
Gisela L. Schulz,Sabine Ludwigs +1 more
TL;DR: In this paper, the delicate interplay between solution processing and the obtained morphology in polythiophenes and low bandgap copolymers is discussed, and the role of morphology has been identified as a key parameter in determining device performance.

Helical polyacetylene—Origins and synthesis
Kazuo Akagi,Taizo Mori +1 more
TL;DR: It is worthwhile to emphasize that the hierarchical spiral morphology involving the primary to higher order structure is generated in a synthetic polymer such as polyacetylene by using N*-LC as an asymmetric polymerization solvent.

Charge transport in the “emeraldine” form of polyaniline
TL;DR: In this article, the conductivity and the dielectric constant of polyaniline were studied in a wide range of frequency (dc, 10 1 -10 5 Hz, 6.5×10 9 Hz), temperature (20K −340K) and protonation level (x ≡[C1]/[N] = 0.0 −0.5).
