Abstract
This disclosure provides compositions of electrochromic dyes, functionalized electrochromic dyes and dye macromers which may be incorporated into electrochromic devices with tailored optical properties. The disclosure provides electrochromic devices having cathodic electrochromic dyes with coupled donor-acceptor structures. The disclosure provides an electrochromic device which reversibly colors from a bleached state to a dark state, wherein the electrochromic device contains at least one dye having an Acceptor-Donor-Acceptor (A-D-A) structure, wherein the dye has cathodic electrochromic properties.
Claims22
An electrochromic device which reversibly colors from a bleached state to a dark state, comprising at least one dye having at least one of an Acceptor-Donor-Acceptor (A-D-A) structure, A-D-D-A structure, A-D-A-D-A structure wherein the dye has cathodic electrochromic properties.
An electrochromic device comprising two electrically conductive coatings deposited on two substrates, wherein at least one of the two substrates is transparent, and the electrochromic device comprises an electrolyte between the two electrically conductive coatings, wherein the device reversibly colors from a bleached state to a dark state, wherein the electrochromic device comprises at least one dye selected from a group which has an Acceptor-Donor-Acceptor (A-D-A) structure, an A-D-D-A structure, or an A-D-A-D-A structure, and has cathodic electrochromic properties.
An electrochromic device comprising two electrically conductive coatings deposited on two substrates, wherein at least one of the two substrates is transparent, and the electrochromic device comprises an electrolyte between the two electrically conductive coatings, wherein the device reversibly colors from a bleached state to a dark state, wherein the electrolyte comprises (a) at least one dye selected from a group which has an Acceptor-Donor-Acceptor (A-D-A) structure, an A-D-D-A structure, or an A-D-A-D-A structure and having cathodic electrochromic properties and (b) at least one anodic dye.
