Electrochromic Devices and Compositions Including Anodic Components As Cathodic Component Counter-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 conductive 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 electrically conductive electrode layer and said second transparent electrically conductive 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,
• 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.
