3,4-ethylenedioxythiophene (EDOT) based donor-acceptor-donor (DAD) type conjugated polymers generally have extraordinary electrochromic properties due to the excellent nature of the EDOT unit. This work investigates the electrochromic properties of such a system; EDOT-Carbazole-EDOT (ECE) based DAD type of conjugated polymer.

Polymer effect in electrochromic behavior of oligomeric viologens
Journal of Applied Polymer Science, 1979AbstractA series of oligomeric viologens were synthesized in order to investigate the polymer effect in electrochromic behavior of viologen compounds. These materials have a lower first‐step reduction potential and a higher second‐step reduction potential compared with monomeric viologens. As a result, they have wider potential separation, where stable

Crystallinity Effects in the Optical Modulation of Electrochromic Devices
MRS Proceedings, 1995AbstractThe electrochromic switching behavior of amorphous and crystalline WO3 thin films was investigated. The films were deposited on ITO-coated Corning 7059 glass substrates by sputtering. X-ray diffraction showed the crystalline film to have a mixed monoclinic/orthorhombic crystal structure.

The Influence of Terminal Effect on the Performance of Electrochromic Windows
Journal of The Electrochemical Society, 1990A simple theory of potential and current distributions developed elsewhere, based on the parallel-plate electrochemical cell under linear kinetics, is applied to electrochromic windows. In our case, only the working electrode has appreciable resistance.

The electrochromic effect in cobalt oxide thin films
Advanced Materials, 1991Communication: Anodic electroprecipitation has been used to deposit thin films of cobalt oxide onto transparent, conducting glass substrates. The electrochromic effect, a reversible color change promoted by an electrochemical reaction, is demonstrated in the films making them of interest, as with WO3, V2O5 and other transition‐metal oxides, for ...

Photoinduced electrochromic effect and its applications to displays
Applied Physics Letters, 1976A liquid solution of an organic donor of the pyrazoline class in a halogenated solvent placed between two transparent electrodes shows blue-color-generating electrochromism whose coloring intensity can be controlled by external illumination. The effect seems to be applicable to optically addressable direct-view passive displays.

The effects of coloured base fabric on electrochromic textile
Coloration Technology, 2011The colour of electrochromic fabric, and its colour transitions, was explored on the basis of variations in underlying fabric colour. A complete understanding of this phenomenon is essential for the fabric’s use in full-colour wearable displays or other applications. Previous work in this area utilised only white-coloured starting materials.

Angewandte Chemie International Edition, 2016
AbstractElectroresponsive structurally colored materials composed of ordered arrays of polyaniline@poly(methyl methacrylate) (PANI@PMMA) core–shell nanoparticles have been successfully prepared. The core–shell nanoparticles were synthesized by deposition of PANI shells on the surfaces of the PMMA cores by the oxidative polymerization of anilinium ...
