Abstract
An electro-optic cell for an electrochromic device includes an electrochromic medium including an electrochromic compound M having at least one reduced state and at least one oxidized state. The electrochromic compound M can act as both the anodic material and the cathodic material in the electro-optic cell. The electrochromic medium can be capable of reversibly attenuating transmittance of light having a wavelength within a predetermined range.
