Abstract
An electrochromic device having an electrochromic medium which includes a compound represented by the following formula:
wherein R1-R10 are the same or different and comprise H, an alkyl, cycloalkyl, polycycloalkyl, heterocycloalkyl, aryl, alkaryl, aralkyl, alkoxy, alkenyl, and/or alkynyl group containing approximately 1 to approximately 50 carbon atom(s), wherein the carbon atom(s) 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; with the proviso that R2 and R7 each comprise at least two carbon atoms, at least one of R2 and R7 comprises less than 2β hydrogen atoms and is void of a benzyl group.
