Microporous organic polymer-induced gel electrolytes for enhanced operation stability of electrochromic devices

Gel electrolytes were synthesized by the formation of microporous organic polymers in the presence of 0.077–0.77 M LiClO4 and N-methylpyrrolidone. Electrochromic devices fabricated using the gel electrolytes showed enhanced operation stability, compared with those fabricated using liquid electrolytes, which is attributable to the efficient separation of working viologens from counting molecules.
