Abstract
The present invention is directed to 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.
