Title:
ELECTROCHROMIC SALTS, SOLUTIONS, AND DEVICES
Document Type and Number:
WIPO Patent Application WO2004000800
Kind Code:
A3
Abstract:
Electrochromic salts of dicationic viologens such as methyl viologen and benzyl viologen associated with anions selected from bis(trifluoromethylsulfonyl)imide, bis(perfluoroethylsulfonyl)imide, and tris(trifluoromethylsulfonyl)methide are produced by metathesis with the corresponding viologen dihalide. They are highly soluble in molten quarternary ammonium salts and together with a suitable reductant provide electrolyte solutions that are used in electrochromic windows.
