Infrared Properties Of Electrochromic Materials
SPIE Proceedings, 1989Thin films of crystalline LiXWO3 exhibit large increases in infrared reflectance (2-16 μm) on lithium insertion, in keeping with the Drude model of free electron reflectance.

Electrochromic properties of conducting polyanilines
Journal of Physics D: Applied Physics, 1989A 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, 1997An 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 ...

Electrochromic Properties Of Phosphotungstic Acid
SPIE Proceedings, 1989The 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.

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, 2018In 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, 1993Abstract 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, 2010New 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

Abstract A novel series of multicolored near-infrared electrochromic aromatic polyimides have been synthesized by a conventional two-step polymerization process. All polymers displayed outstanding thermal stability, i.e. 20 wt% loss in excess of 593 °C in nitrogen and high char yields (higher than 68% at 750 °C). In addition, the polymer films showed

Polysulfurated Pyrene‐Cored Dendrimers: Luminescent and Electrochromic Properties
Chemistry – A European Journal, 2008AbstractWe have synthesized a novel class of dendrimers, consisting of a polysulfurated pyrene core with appended poly(thiophenylene) dendrons (PyG0, PyG1, and PyG2, see Scheme 1), which exhibit remarkable photophysical and redox properties. In dichloromethane or cyclohexane solution they show a strong, dendron‐localized absorption band with a maximum ...
