    摘要: A process for preparing a heteroaromatic compound having a heteroaromatic nucleus substituted with one or more ether groups comprising the step of: condensing at least one hydroxy-group of a compound having said heteroaromatic nucleus, said at least one hydroxy group (—OH) being substituted at &agr;- or &bgr;-positions with respect to a heteroatom of said heteroaromatic nucleus, with an alcohol containing one or more primary or secondary alcohol groups, optionally substituted with nitro, amide, ester, halogen, cyano or (hetero)aromatic groups, using the redox couple of a triaryl- or trialkylphosphine and an azodioxo-compound at a temperature between −40° C. and 160° C.

    摘要: 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.
