An electrochromic mirror (10) comprises an reflective electrically conductive substrate and a transparent electrically conductive substrate, a layer of an ion conductive material (14) disposed therebetween and at least one electrochromic chromogenic layer (13) disposed either between the ion conductive material layer and the reflective electrically conductive substrate or between the ion conductive material layer and the transparent electrically conductive substrate, said electrochromic chromogenic layer containing a compound having a viologen structure represented by the formula wherein X− and Y− may be the same or different and each indicate a counter anion selected from the group consisting of a halogen anion, ClO4−, CH3COO−, and CH3(C6H4)SO3−. The inventive mirror can be put in a various applications such as an antiglare mirror for an automobile and a decorative mirror for out door use.
