Abstract
The present invention relates to electrochromic devices and compositions, that include a polymer matrix or thickener, that includes poly((diallyldimethylammonium bis(substituted-sulfonyl)imide X−)) polymer, where each X− independently is an anion represented by the following Formula (A), With reference to Formula (A), R9 and R10 are each independently selected from fluorine, linear or branched fluorinated alkyl, or linear or branched perfluorinated alkyl.
Claims20
An electrochromic device comprising:
- (a) a first substrate having a surface comprising a first transparent electrode layer;
- (b) a second substrate having a surface comprising a second transparent electrode layer,
- wherein said first transparent electrode layer and said second transparent electrode layer are in opposing spaced opposition;
- and
- (c) an electrochromic layer interposed between said first transparent electrode layer and said second transparent electrode layer, wherein said electrochromic layer comprises,
- (i) an electrochromic material comprising a cathodic component having cationic charge, wherein said cathodic component further comprises counter-anions, wherein each counter-anion of said cathodic component is an anodic component having an anion covalently bonded thereto, and wherein said cathodic component is free of counter-anions other than said anodic component having an anion covalently bonded thereto,
- (ii) an optional electrolyte, and
- (iii) a polymer matrix, wherein said polymer matrix comprises a polymer, wherein said polymer comprises poly(diallyldimethylammonium X−), wherein each X-independently is an anion represented by the following Formula (A),
- wherein R9 and R10 are each independently selected from fluorine, linear or branched fluorinated alkyl, or linear or branched perfluorinated alkyl.
