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

Organic electronic materials: recent advances in the DFT description of the ground and excited states using tuned range-separated hybrid functionals.
TL;DR: This Account highlights how these failures can be traced back to the delocalization error inherent to semilocal and global hybrid functionals, which leads to the spuriousDelocalization of electron densities and an overestimation of conjugation.
