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:

Band gap modulation in polythiophene and polypyrrole-based systems
TL;DR: The structural and electronic properties of polythiophene and polyprrrole-based systems have been investigated using first-principles calculations both in periodic and oligomer forms and trends in the binding energy are similar for both periodic and molecular calculations.

Principles of Structural Design of Conjugated Polymers Showing Excellent Charge Transport toward Thermoelectrics and Bioelectronics Applications
TL;DR: The aspects of synthetic design and the consequences of modifications of the chemical structure on the charge transport in selected second-generation conjugated polymers are reviewed and the prospect of a purposeful design of new materials for these two emerging fields is discussed.

Toward Purple-to-Green-to-Transmissive-to-Black Color Switching in Polymeric Electrochrome
TL;DR: In this paper, a 3,4-ethylenedioxythiophene (EDOT)-based donor-acceptor electroactive monomer (HCQE) bearing carbazole subunit is synthesized, and then the corresponding polymer is directly deposited onto ITO/glass surface via electrochemical process.

Characterization of Piezoresistive PEDOT:PSS Pressure Sensors with Inter-Digitated and Cross-Point Electrode Structures
TL;DR: The piezoresistive pressure sensors with a single carrier-conducting pathway, i.e., IDE without b-ITO and CPE structures, exhibited a small relaxation time and a superior reversible operation, which can be advantageous for fast piezoreistive response applications.

Conjugated Polymers: The Interplay Between Synthesis, Structure, and Properties
C. B. Gorman,R. H. Grubbs +1 more
TL;DR: In this article, it was shown that oxidizing or reducing the backbone (doping) of polyacetylene at a level equivalent to removing/adding an electron in one out of every 5-15 repeat units, increased the conductivity of the matrix by many orders of magnitude.
