Electrochromic Devices and Compositions Including Cathodic Zwitterions

The present invention relates to electrochromic devices and compositions, which include a cathodic component that includes cathodic zwitterions, where an anion is covalently bonded by a divalent linking group to a pyridinium nitrogen of the cathodic component. Each covalently bonded anion is indepen...

Beschreibung
Zusammenfassung:	The present invention relates to electrochromic devices and compositions, which include a cathodic component that includes cathodic zwitterions, where an anion is covalently bonded by a divalent linking group to a pyridinium nitrogen of the cathodic component. Each covalently bonded anion is independently represented by the following Formula (III) or Formula (IV):With reference to Formula (III) and Formula (IV), R6 and R7 are in each case independently selected from divalent linear or branched alkane linking group, and for Formula (IV), R8 is selected from fluorine, linear or branched fluorinated alkyl, or linear or branched perfluorinated alkyl.
