The subject invention pertains to electrochromic polymers and
polymer electrochromic devices. In a specific embodiment, two complementary polymers can be matched and incorporated into dual
polymer electrochromic devices. The anodically coloring polymers in accordance with the subject invention can allow control over the color, brightness, and
environmental stability of an electrochromic window. In addition, high device contrast ratios,
high transmittance changes, and
high luminance changes can be achieved, along with half-second switching times for
full color change. Also provided are
electrochromic devices such as advertising signage, video monitors, stadium scoreboards, computers, announcement boards, warning systems for
cell phones, warning / information systems for automobiles, greeting cards, electrochromic windows, billboards, electronic books, and
electrical wiring. The subject invention also provides for the use of complementary electrochromic polymers in the manufacture of electrochromic devices. In some embodiments, the devices of the invention can be prepared using
metal vapor deposition or line patterning.
