Electrochromic devices having an electron shuttle

An electrochromic device, comprising:

• a first substantially transparent substrate having an electrically conductive material associated therewith;
• a second substrate having an electrically conductive material associated therewith;
• and
• an electrochromic medium contained within a chamber positioned between the first and second substrates which comprises:
• at least one solvent;
• an anodic electrochromic material;
• a cathodic electrochromic material;
• an electron shuttle comprising a similar chromophore as at least one of the anodic and cathodic electrochromic materials, wherein the electron shuttle serves to decrease switching time of the electrochromic device relative to the same without the electron shuttle;
• and
• wherein the electrochromic medium comprises a cross-linked polymer matrix.
