Abstract

Official abstract text for this publication.

An electrochromic element is provided. The electrochromic element includes a first electrode, a second electrode, an electrolyte disposed between the first electrode and the second electrode, a first layer overlying the first electrode, and a second layer overlying the second electrode. The first layer contains an oxidizable color-developing electrochromic compound. The second layer contains a compound having the following formula (1): wherein each of R 1 to R 5 independently represents a hydrogen atom, a halogen atom, or a monovalent organic group, and at least one of R 1 to R 5 has a functional group directly or indirectly bindable to hydroxyl group.

First claim

Opening claim text (preview).

What is claimed is: 1 . An electrochromic element comprising: a first electrode; a second electrode; an electrolyte disposed between the first electrode and the second electrode; a first layer overlying the first electrode, containing an oxidizable color-developing electrochromic compound; and a second layer overlying the second electrode, containing a compound having the following formula (1): wherein each of R 1 to R 5 independently represents a hydrogen atom, a halogen atom, or a monovalent organic group, and at least one of R 1 to R 5 has a functional group directly or indirectly bindable to hydroxyl group. 2 . The electrochromic element of claim 1 , wherein the monovalent organic group is selected from the group consisting of an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heteroaryl group, an alkoxy group, an aryloxy group, and a heteroaryloxy group. 3 . The electrochromic element of claim 1 , wherein R 3 has the functional group directly or indirectly bindable to hydroxyl group. 4 . The electrochromic element of claim 1 , wherein the functional group directly or indirectly bindable to hydroxyl group is selected from the group consisting of phosphonic acid group, phosphoric acid group, carboxylic acid group, sulfonyl group, silyl group, and silanol group. 5 . The electrochromic element of claim 1 , wherein the functional group directly or indirectly bindable to hydroxyl group has at least one group selected from the group consisting of an alkyl group, an aryl group, and an alkyl-group-substituted aryl group. 6 . The electrochromic element of claim 1 , further comprising a conductive or semiconductive nanostructural body disposed on the second electrode, wherein the compound having the formula (1) is bound or adsorbed to the conductive or semiconductive nanostructural body. 7 . The electrochromic element of claim 1 , wherein the second layer is a counter electrode layer.
