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

Highly Bendable Large-Area Printed Bulk Heterojunction Film Prepared by the Self-Seeded Growth of Poly(3-hexylthiophene) Nanofibrils
Jin Young Oh,Minkwan Shin,Tae Il Lee,Woo Soon Jang,Yu Jeong Lee,Chang Su Kim,Jae-Wook Kang,Jae Min Myoung,Hong Koo Baik,Unyong Jeong +9 more
TL;DR: In this paper, the authors applied a C&H process with a P3HT/PCBM m-xylene solution to generate P3H:PCBM nanofibril composite films and found that the hole transport was 2.6 times faster in the thickness direction and 6.5 times more conductive in the in-plane direction.

Control of Chirality and Electrochromism in Copolymer-Type Chiral PEDOT Derivatives by Means of Electrochemical Oxidation and Reduction
Yong Soo Jeong,Kazuo Akagi +1 more
TL;DR: In this article, the electrochromic and morphological changes of chiral poly(ethylenedioxythiophene) derivatives upon electrochemical doping and dedoping were investigated, and it was found that the helically twisted chain and/or helically π-stacked structure formed in the neutral PEDOT derivative are suppressed in the oxidized state, where the main chain becomes planar due to a formatio...

Triphenylene-Based Polymers for Blue Polymeric Light Emitting Diodes
TL;DR: In this article, a series of conjugated blue emitting polymers containing triphenylene as repeating unit for PLEDs were synthesized and the photophysical properties of the polymers were studied based on the different main chains and substituents.

Conducting Polymers in Neural Stimulation Applications
TL;DR: In this article, the authors explored several conducting polymers (ICPs) as new electrode materials for neural interfaces, such as polypyrrole (PPy), polyaniline (PANi), and poly(3,4-ethylenedioxythiophene) (PEDOT) polymers may offer the organic, improved bionic interface that is necessary to promote biocompatibility in neural stimulation applications.
