Flexible electrofluorochromic devices were prepared from two electrochromic and AEE-active (AEE: aggregation-enhanced emission) cyanoarylamine-containing high-performance polymers, exhibiting the highest contrast ratio (If/If0) of 151.9 at a low working potential.

This award account focuses on metallo-supramolecular polymers (MSPs), which are composed of metal ions and multitopic ligands, as a new branch coordination polymers. Their high solubility in polar solvents, such methanol or water their amorphous nature the solid state, enabled formation thin layers MSPs with uniform thickness an electrode surface by spin- spray-coating polymer solution, resulti...

Stretchable Electrochromic Displays In article number 2204103, Huajing Fang, Hong Wang, Pooi See Lee, and co-workers report a novel self-powered light-adaptable stretchable electrochromic display using WO3 on phosphorescent conductor as the electrode, integrated in parallel with Zn/carbon electrodes topped ZnCl2-based organohydrogel. This geometrically designed can exhibit “on/off” states both ...

A novel near-infrared (NIR) electrochromic polyelectrolyte consisting of anthraquinone imide (AQI) pendants and a poly(1-vinylimidazole bromide) main chain was synthesized via radical polymerization. Its AQI content was varied by copolymerization with 1-vinyl-3-butylimidazole bromide to improve the processability of the polymer as well as the monomer conversion. The electrochemical and electroc...

We have systematically studied the self-organization of poly(3-hexylthiophene) (P3HT), an electrochromic material, upon control of the solvent evaporation rate. We characterized these polymer films using atomic force microscopy and X-ray diffraction measurements. Well-ordered P3HT structures were developed after solvent annealing; these highly crystalline structures exhibited enhanced electroch...

constants of crystalline WO 3 deposited by magnetron sputtering" (1999). Crystalline WO 3Ϫx is an infrared ͑IR͒ electrochromic material having possible applications in satellite thermal control and IR switches. Optical constants of electrochromic materials change upon ion intercalation, usually with H ϩ or Li ϩ. Of primary concern for device design are the optical constants in both the intercalat...

A series of compounds, featuring an ethenylic bridge and quinoline and isoquinoline end capping units possessing systematically varied substitution patterns, were prepared as molecular materials for electrochromic applications. The different structures were optimized in order to maximize the electrochromic contrast in the visible region, mostly by achieving a completely UV-absorbing oxidized st...

This work reports the preparation, characterization and application as both electrochromic materials and electrochemical sensors of novel materials: carbon nanotubes/ruthenium purple nanocomposites. Using an innovative route based on a heterogeneous electrochemical reaction involving iron oxide species encapsulated within the cavities of the carbon nanotubes, the nanocomposite materials were ob...

Encapsulation of molybdenum oxide MoO3 into ordered mesoporous silica materials is demonstrated using different synthetic routes. Either supramolecular polyoxometalates of the “Müller type” or Na2MoO4 were used as precursors. Molybdenum oxide (MoO3)-silica hybrid materials were characterized using nitrogen-sorption experiments, transmission electron microscopy, small-angle X-ray scattering, and...
