An electrochromic medium (124) for use in an electrochromic device (100) comprising a substrate (112) having a front and rear surface (112a and 112b), a second substrate (114) having a front and rear surface (114a and 114b), and a chamber (116), substrates that may be coated with electrically conductive materials (118 and 120) having a bonding sealing member (122), at least one solvent at cathodic electroactive material, an anodic electoactive material, an optional beneficial agent, where at least one of the cathodic electroactive material, anodic electroactive material, and/or beneficial agent is associated with a solubizing moiety which serves to increase solubility of the associated material or agent relative to the same without the solubizing moiety.
