Functionalized Poly(azulenes) and Their Electrochromic Properties

ChemistrySelect, 2023
Abstract In this work, five 2‐ or 6‐ functionalized azulenes are electropolymerized to form azulene homopolymers. All five poly(azulenes) films exhibited electrochromism, with a two‐stage oxidation corresponding to the formation of the azulenium cation and the polaron, respectively.

Electrochromic Properties Of Phosphotungstic Acid

SPIE Proceedings, 1989
The electrochromic behavior of phosphotungstic acid (PWA), a heteropoly compound was investigated. The electrochemical and in-situ spectroelectrochemical measurements showed that by electrochemical oxidation and reduction, phosphotungstic acid can be bleached and colored, respectively.

Electrochromic properties of conducting polyanilines

Journal of Physics D: Applied Physics, 1989
A study has been made of the electrochromic behaviour of polyaniline films of potential use in passive display devices, and a preliminary examination of the properties of substituted polyanilines has also been carried out. Films of 'emeraldine-type' conducting polyanilines have been grown electrochemically from aqueous solutions onto glass substrates ...

Electrochromic properties of polycarbazole films

Polymer, 1997
An attempt has been made to investigate the electrochromic properties of polycarbazole (PCARB) films. Both the electrochemical current response and optical transmittance of an electrochromic cell fabricated using PCARB electrochemically deposited onto an indium-tin-oxide (ITO) glass as an anode and platinum as a cathode have been experimentally ...

The synthesis and electrochemical properties of anodic electrochromic materials phenothiazine derivatives and their electrochromic devices

Displays, 2010
Abstract In order to develop novel electrochromic materials, a series of N-substituted phenothiazine derivatives (PDs) were synthesized via S N 2 reaction and characterized by NMR, IR spectroscopy. Their electrochemical properties were investigated using cyclic voltammetry and their spectrochemical properties were examined by UV–vis spectroscopy.

Ligand Impact on Monolayer Electrochromic Material Properties

ACS Applied Materials & Interfaces, 2018
In this study, we present a range of efficient highly durable electrochromic materials that demonstrate excellent redox and lifetime stability, sufficient coloration contrast ratios, and the best-in-class electron-transfer constants. The materials were formed by anchoring as little as a monolayer of predefined iron complexes on a surface-enhanced ...

Electrochromic properties of dodecyclbenzenesulfonate doped poly(pyrrole)

Electrochimica Acta, 1993
Abstract The galvanostatic synthesis of dodecylbenzenesulfonate doped poly(pyrrole), PPYDBS, on ITO electrodes produces homogeneous films which show a color change from yellow to dark blue when cycled in aqueous KCl between −0.75 and 1.00 V (vs. sce ).

Designed Synthesis of Ferrocenylanthraquinones and Their Bifunctional Electrochromic Properties

Organic Letters, 2010
New bifunctional electrochromic systems were developed by combination of reductive anthraquinone with oxidative ferrocene redox systems. The resultant ferrocenylanthraquinones demonstrated enhanced stability in electrochromic performance through the concomitant reductive electrochromism and oxidative counting action. The displayed colors were dependent

Electrochromic Properties of Tungsten-Titanium Oxide Films

Journal of Nanoscience and Nanotechnology, 2012
The last decade has seen great in electrochromic (EC) technology for smart windows and displays. In this study, WTiOx films formed from TiO2 and WO3 were deposited onto ITO glass with a sheet resistance of 10 Omega cm and on silicon substrates, by pulsed magnetron sputtering using a W and Ti alloy target.
