Abstract: An electro-optic element includes a first electroactive film including a first electroactive component sequestered adjacent to a first electrically conductive layer and a second electroactive film including a second electroactive component sequestered adjacent to a second electrically conductive layer. At least one of the first electroactive film and the second electroactive film is capable of reversibly attenuating transmittance of light having a wavelength within a predetermined wavelength range. The first electroactive component can include a first oxidation state and at least a second oxidation state. An amount of the first electroactive component relative to the second electroactive component can be configured to limit formation of the second oxidation state of the first electroactive component.

Abstract: An electro-active device is disclosed that may comprise a buffer immobilized on one or more films. The electro-active device may comprise a first substrate, a second substrate, a first electrode, and a second electrode. The first and second substrates may be disposed in a spaced apart relationship. Further, the first electrode may be associated with the first substrate and the second electrode may be associated with the second substrate. Additionally, a cathodic film may be associated with one electrode and an anodic film may be associated with the other electrode. The anodic film may comprise an anodic compound immobilized thereon and the cathodic film likewise may comprise a cathodic compound immobilized thereon. Further, a buffer component may be immobilized on the cathodic film and/or the anodic film.

Abstract: The electrochromic device includes a first substantially transparent substrate coupled to a first transparent electrode, a second substrate coupled to a second electrode, and an electrochromic medium. The electrochromic medium includes at least one solvent and/or an electrolyte gel, at least one cathodic material, and at least one anodic material. The cathodic material can be a cathodic organic framework electroactive material and/or the anodic material can be an anodic organic framework electroactive material. At least one of the anodic and cathodic organic framework electroactive materials is electrochromic.
