1. A distate interior electrochromic mirror, comprising:

  • a first substantially transparent substrate having an electrically conductive material associated therewith;

    a second substrate having an electrically conductive material and an at least partially reflective material associated therewith;

    an electrochromic medium contained within a chamber positioned between the first and second substrates which comprises;

    at least one solvent;

    at least one anodic material;

    at least one cathodic material, wherein both of the anodic and cathodic materials are electroactive and at least one of the anodic and cathodic materials is electrochromic;

    a cross-linked polymer matrix;

    wherein, in a first state, the electrochromic medium exhibits a maximum light transmission; and

    wherein, in a second state, attenuation occurs to a significant extent in at least one of visible radiation and near-infrared radiation; and

    wherein the distate electrochromic device does not materially exhibit segregation after being maintained in the second state for 24 continuous hours at 50 degrees centigrade.
