Electrochromic devices and compositions including anodic component anions

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) a cathodic component,
• (ii) an anodic component comprising an anodic component anion selected from at least one anodic component anion represented by the following Formula (I) or Formula (II),
• wherein for Formula (I), R1 is selected from divalent linear or branched alkane linking group, and
• wherein for Formula (II), R2 is selected from divalent linear or branched alkane linking group, and R3 is selected from fluorine, linear or branched fluorinated alkyl, or linear or branched perfluorinated alkyl,
• (iii) an optional electrolyte, and
• (iv) a polymer matrix,
• wherein said anodic component further comprises a counter-cation.
