TL;DR: In this article, a series of experiments on the physics and chemistry of polymers derived from pyrroles were conducted, showing that the oxidation of neutral insulating polypyrrole (PP0) to its conducting counterpart (PP+) is a multistep process and that the conductivity of the polymers increases only in the early stages of oxidation, whereas significant changes in the optical and EPR properties occur in later stages of the oxidation when no further changes in conductivity take place.
Abstract: A series of experiments on the physics and chemistry of polymers derived from pyrroles show that the oxidation of neutral insulating polypyrrole (PP0) to its conducting counterpart (PP+) is a multistep process. In particular, the conductivity of the polymers increases only in the early stages of oxidation, whereas significant changes in the optical and EPR properties occur in later stages of the oxidation when no further changes in the conductivity take place. The early stages of oxidation lead to an ionic (PP+ anion−) polymer and the later stages of oxidation result in chemistry at the nitrogen atoms of the pyrrole rings. Similar behavior is observed for all the oxidized pyrrole polymers independent of the method of oxidation.

TL;DR: In this paper, a polymer memory device with an active layer consisting of conjugated poly3-hexylthiophene and gold nanoparticles capped with 1-dodecanethiol sandwiched between two metal electrodes is presented.
Abstract: Electrical bistability is demonstrated in a polymer memory device with an active layer consisting of conjugated poly3-hexylthiophene and gold nanoparticles capped with 1-dodecanethiol sandwiched between two metal electrodes. The device was fabricated through a simple solution processing technique and exhibited a remarkable electrical bistable behavior. Above a threshold voltage the pristine device, which was in a low conductivity state, exhibited an increase in conductivity by more than three orders of magnitude. The device could be returned to the low conductivity state by applying a voltage in the reverse direction. The electronic transition is attributed to an electric-field-induced charge transfer between the two components in the system. The conduction mechanism changed from a charge-injection-controlled current in the low conductivity state to a charge-transport-controlled current in the high conductivity state. In the high conductivity state the conduction was dominated by a field-enhanced thermal excitation of trapped charges at room temperature, while it is dominated by charge tunneling at low temperatures. The device exhibited excellent stability in both the conductivity states and could be cycled between the two states for numerous times. The device exhibits tremendous potential for its application as fast, stable, low-cost, high storage density nonvolatile electronic memory. © 2006 American Institute of Physics.

TL;DR: In this paper, a bifunctional liquid additive was added to the light-emitting layer to improve the performance of light emitting electrochemical cells (LEEECs).
Abstract: The device performance of light‐emitting electrochemical cells is improved by adding a bifunctional liquid additive into the light‐emitting layer. Because of the surfactant‐like character of the additive, the light‐emitting layer exhibits a high surface area bicontinuous three‐dimensional network morphology. The semiconducting polymer forms a continuous network phase enabling electronic transport of injected electron and holes: the electrolyte forms a continuous network phase enabling fast ion transport; the nm length scale of the phase separated network enables rapid, effective transport of the ions into the conducting polymer during electrochemical doping.
