Abstract

Official abstract text for this publication.

An electrochromic element is provided. The electrochromic element includes a first electrode, a second electrode facing the first electrode with a gap therebetween, and a color developing layer disposed between the first electrode and the second electrode. The color developing layer includes an electrochromic compound that develops and discharges color by a redox reaction and a compound having an adsorption group adsorptive to the first electrode.

First claim

Opening claim text (preview).

The invention claimed is: 1. An electrochromic element comprising: a first electrode; a second electrode facing the first electrode with a gap therebetween; and a color developing layer disposed between the first electrode and the second electrode, the color developing layer comprising: a first electrochromic layer in contact with the first electrode; and an electrolyte layer comprising an electrolyte, wherein the first electrochromic layer comprises: a first electrochromic compound that develops and discharges color by a redox reaction, and that develops color by an oxidation reaction; and a compound having an adsorption group adsorptive to the first electrode, wherein each of the first electrochromic compound and the compound having an adsorption group has a polymerizable functional group, and wherein the first electrochromic layer comprises a copolymer of the first electrochromic compound and the compound having an adsorption group. 2. The electrochromic compound of claim 1 , wherein the first electrochromic compound comprises a polymerizable compound having a triarylamine structure. 3. The electrochromic element of claim 1 , wherein the color developing layer further comprises a second electrochromic layer in contact with the second electrode, wherein the second electrochromic layer comprises a second electrochromic compound that develops color by a reduction reaction. 4. The electrochromic element of claim 3 , wherein the second electrochromic compound comprises at least one of a viologen compound and a dipyridine compound. 5. The electrochromic element of claim 1 , wherein the adsorption group adsorptive to the first electrode is a phosphate group. 6. The electrochromic element of claim 1 , wherein the first electrode comprises indium tin oxide.
