Patent Images
1. An electrochromic medium for use in an electrochromic device, comprising:
- at least one solvent;
an anodic material;
a cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic; and
an ultraviolet stabilizing material, wherein the ultraviolet stabilizing material includes a solublizing moiety which serves to increase solubility of the ultraviolet stabilizing material relative to the same without the solublizing moiety.
