“…After 1 immersed in Fe 3+ or Cu 2+ , the above three bands deformed slightly (Figures , S21 and S22), caused by Fe 3+ or Cu 2+ ions coordinated to the open nitrogen atoms, then the aromatic system of the pyridine ring was perturbed. The perturbation of the aromatic system led to deformation of the distribution of π-electron density in the ring . Therefore, obtained results suggested that Fe 3+ or Cu 2+ ions perturbed the electron density of remaining uncoordinated pyridyl, so 1 exhibited weak bonding to Fe 3+ or Cu 2+ ions.…”

“…Due to π‐electron conjugation system, porphyrins display good electronic and optical properties. Oksuz and coworkers have reported the use of PTs to improve the electrochromism of porphyrins . Copolymerization of thiophene monomers (3‐methylthiophene and 3‐hexylthiophene) with meso ‐tetrakis(2‐thienyl)porphyrin and meso ‐tetrakis(2‐thienyl) porphyrinzinc(II)) by electropolymerization generated copolymers films on the electrode surface.…”

A rapid and persistent switching from pale yellow to gray was observed upon application of the anodic potential . Lower oxidation state of copolymers of porphyrin monomer with both 3‐methylthiophene and 3‐hexylthiophene displayed higher stability up to 1000 cycles with voltage sweeping and good optical properties for solid‐state electrochromic devices.…”

Semiconducting polythiophenes display electroactive properties which make them excellent candidates for applications as electroactive materials. Ability to undergo doping and to switch between different oxidation states allow tuning the chemical and physical properties of polythiophenes. Furthermore, the ability to integrate polythiophenes into copolymers, hybrid composites with metals and inorganic materials make them useful in electronic and biomedical applications. The capability to vary the properties of the final material with low production cost and high processability into thin films makes polythiophenes desirable materials for many applications. © 2017 Wiley Periodicals, Inc.

Electrochromic materials have extensively been investigated because of their potential fields of application, with a significant growing interest in expanding the provided colorations. However, among all palette of colors, colorless electrochromic devices (ECDs) that provide neutral-grayish colorations with a simple configuration remain a key challenge. The present study reports on the synthesis of asymmetrically 1-alkyl-1'-aryl-substituted viologens and their incorporation in PVA-borax gel polyelectrolytes for ECDs that constitute the simplest device architecture (glass/TCO/EC gel/TCO/glass). We demonstrate herein that these EC gels based on single asymmetric viologens provide more neutral-colored state than their corresponding symmetric viologens (a* and b* ≤ |15|), while maintaining satisfactory colorless bleached state (%T > 70% in the whole visible range), transmittance changes (i.e., ∼60%) and cyclability (i.e., ∼15 000 cycles). Additionally, the effect of the solvent on the observed coloration has also been investigated. This easy-to-make neutral-grayish color ECDs may significantly extend the potential of the electrochromic technology, because they adapt better aesthetically to the surrounding environment, as they are easier to implement in different applications.
