1. An electrochromic medium comprising two or more electroactive compounds, at least one of said electroactive compounds being a coupled electrochromic compound comprising a first anodic monomeric electrochromic compound coupled by a bridge comprising a covalent bond or an intervening hydrocarbon structure optionally containing one or more heteroatoms, to a second anodic monomeric electrochromic compound, and optionally additional monomeric electrochromic compounds such that electronic communication is exhibited between said anodic monomeric compounds.
