摘要

An electrochromic device having an electrochromic medium comprising: a material represented by the following formula: wherein X comprises N-R₁₀, O, or S; wherein R₁-R₁₀ are defined herein with the proviso that at least one of R₅ and R₁₀ comprises an alkyl, cycloalkyl, polycycloalkyl, heterocycloalkyl, aryl, alkaryl, aralkyl, alkoxy, alkenyl, and/or alkynyl group containing 4 to approximately 50 carbon atoms, wherein at least one of the carbon atoms may be a linking group to, or part of, a halogen, a N, O, and/or S containing moiety, and/or one or more functional groups comprising alcohols, esters, ammonium salts, phosphonium salts, and combinations thereof, and wherein at least one of R₅ and R₁₀ is void of any beta hydrogen atoms.
