TL;DR: In this article, a family of four novel selenophene-EDOT oligomers were synthesized using Stille coupling and electropolymerized to form highly stable conducting hybrid polymers with excellent electrochromic properties.

TL;DR: In this paper, a large circular dichroism at 1310−1550 nm was induced when the stacked naphthalene diimide chromophores in the chiral gels were reduced to the radical anion state.
Abstract: Chiroptical switching materials in the visible and near-infrared spectral regions have been realized using a low molecular weight gel as a chiral scaffold and electrochromic chromophores as a stimulus-responsive trigger and operate as a result of the change in the electronic states of the chromophores within the chiral gel. N,N′-Bis(4-phenyl-2,3,4,6-tetra-O-acetyl-β-d-glucopyranoside)-1,4,5,8-naphthalenetetracarboxylic diimide, synthesized by imidization of 1,4,5,8-naphthalenetetracarboxylic dianhydride with a sugar-bearing amine, can form stable chiral gels at room temperature. The redox-active gels exhibited reversible and drastic changes in circular dichroism in the visible and near-infrared spectral region between the three redox states (neutral, radical anion, dianion) of the naphthalene diimide chromophore. A large circular dichroism at 1310−1550 nm was induced when the stacked naphthalene diimide chromophores in the chiral gels were reduced to the radical anion state.

TL;DR: In this article, the growth of gold-based nanoparticles and thin films was studied by depositing gold on glass slides and on SnO2 base layers, where gold was deposited on heated and non-heated substrates, where the latter were also postheated, with a temperature range between 25oC and 140oC.

TL;DR: In this article, the change in film color which occurs in the redox reaction of the film was investigated in detail as a function of electrode potential and the charge consumed in the reaction.
Abstract: Polypyrrole films prepared by anodic polymerization of pyrrole on Pt or SnO2-coated glass show redox behavior in aqueous electrolyte solutions containing a supporting electrolyte alone. Transfer of electrolyte anions into and from the film is involved in the redox reaction similarly with acetonitrile solutions already reported. Insertion of divalent anions into the film occurs in two steps but that of monovalent anions in one step, as judged from corresponding cyclic voltammograms. The change in film color which occurs in the redox reaction of the film was investigated in detail as a function of electrode potential and the charge consumed in the redox reaction. Polypyrrole is a promising material for electrochromic display devices.
