A series of organosoluble polyamides based on N-phenothiazinylphenyl redox units showing anodically electrochromic characteristics both in the near-infrared (NIR) and visible light regions were prepared from the phosphorylation polyamidation reactions of a newly synthesized diamine monomer, 4,40-diamino-40 0-N-phenothiazinyltriphenylamine, with various dicarboxylic acids. These polymers were re...

An in situ colorimetric method, based on the CIE (Commission Internationale de l'Eclairage) system of colorimetry, has been applied to the study of the electrochromic N,N ́-bis(n-heptyl)-4,4 ́-bipyridylium (‘di-n-heptyl viologen’) system in aqueous solution on transmissive ITO/glass substrates. On electrochemical reduction of the di-n-heptyl viologen di-cation, the purple di-n-heptyl viologen rad...

A redox series of cyclometalated platinum complexes based on a dinuclear motif linked by acetamidato (aam) bridging ligands, [Pt2 (μ-aam)2 (ppy)2 ] (ppy(-) =2-phenylpyridinate ion), has been synthesized. The complexes in this series are easily oxidized and reduced by both electrochemical and chemical methods, and this is accompanied by multistep changes in their optical properties, that is, mul...

Abstract With the increasing interest in application of electrochromism to flexible and wearable electronics recent years, electrochromic devices (ECDs) that can function at extreme temperatures are required. However, functionalities ECDs severely hampered by inadequate choice electrolytes, which might ultimately result performance fading during low‐ high‐temperature operations. Here, we develo...
