TL;DR: In this article, the authors worked in a private office with switchable electrochromic windows, manually operated Venetian blinds, and dimmable fluorescent lights, and found that the electrics reduced the incidence of glare compared to working under a fixed transmittance (60%) condition.

TL;DR: In this paper, a new photoelectrochromic device with excellent coloring and bleaching characteristics was developed, where the electrochromic layer and the photoactive layer were situated on the same TCO-coated glass substrate (TCO: transparent conductive oxide).

TL;DR: A detailed voltammetric and coulometric study of both the conditions for electrodeposition from ferric ferricyanide solution, of Prussian Blue film on Pt, and of potential sweeps of the deposited film in KCl solution alone is reported in this article.

TL;DR: In this paper, a model is proposed based on the observed microstructure that explains the source of overstoichiometric oxygen and ion transport in these films, and the model is used to explain the redox currents, the efficiency of these films to color, and their optical properties were influenced by the processing conditions employed and the resulting micro-structure.

TL;DR: Electrochromic materials are engineering of an organic π-electron structure-based EM as a unique hydrogen sulfide (H2S)-responsive chromophore amenable to build H2S-activatable fluorescent probes ( 12+-semiconducting polymer nanoparticles, 12+-SNPs) for in vivo H 2S detection.
Abstract: Electrochromic materials (EMs) are widely used color-switchable materials, but their applications as stimuli-responsive biomaterials to monitor and control biological processes remain unexplored. This study reports the engineering of an organic π-electron structure-based EM (dicationic 1,1,4,4-tetraarylbutadiene, 12+) as a unique hydrogen sulfide (H2S)-responsive chromophore amenable to build H2S-activatable fluorescent probes (12+-semiconducting polymer nanoparticles, 12+-SNPs) for in vivo H2S detection. We demonstrate that EM 12+, with a strong absorption (500–850 nm), efficiently quenches the fluorescence (580, 700, or 830 nm) of different fluorophores within 12+-SNPs, while the selective conversion into colorless diene 2 via H2S-mediated two-electron reduction significantly recovers fluorescence, allowing for non-invasive imaging of hepatic and tumor H2S in mice in real time. Strikingly, EM 12+ is further applied to design a near-infrared photosensitizer with tumor-targeting and H2S-activatable abilit...
