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

Polaron dynamics with off-diagonal coupling: beyond the Ehrenfest approximation
TL;DR: The variational method with importance sampling is employed to investigate temperature effects on exciton transport using the multi-D2Ansatz, and it is demonstrated that the variational approach is valid in both low and high temperature regimes.

A Scheme for the Evaluation of Electron Delocalization and Conjugation Efficiency in Linearly π-Conjugated Systems
TL;DR: It will be shown that the reduced conjugation efficiency, within the NBO-based model presented in this work, can be related to the orbital interaction pattern along the π-conjugated chain.

Ion transport and degradation studies of a polyaniline-modified electrode using SECM
TL;DR: In this article, the morphology and ion transport characteristics of polyaniline (PANI) films on a platinum electrode were investigated using scanning electrochemical microscopy method (SECM), where an ultramicroelectrode tip was positioned close to the surface of a PANI-modified substrate electrode, and the current signal at the tip and substrate electrodes, during a substrate potential step or linear sweep were monitored simultaneously.
