ABSTRACT:
An electrochromic device comprising a pair of glass, plastic plates or plastic films At least one plate or film, is provided with an electrically conductive coating. At least one plate or film and its conductive coating are transparent and the other may be mirrored. The plates or films are joined together and form a volume filled with an electrochromic medium which comprises at least one reducible electrochromic substance OX2and at least one oxidizable electrochromic substance RED1. The OX2corresponds to the formulain which R201and R202, each are alkyl, cycloalkyl, alkenyl, aralkyl, aryl, −[C(PQ)]−or a bivalent bridge B, Z201is a bivalent radical of the formulae CR210R211, O, C═O or o-phenylene, R210and R211, each are hydrogen, methyl or ethyl, or CR210R211is C3- to C7-cycloalkane-1,1-diyl. The rings C, D, E and F, each may be substituted by up to 4 alkyl and/or alkoxy radicals, or respectively, may be linked via a —(CH2)4— or —CH═CH—CH═CH— bridge. P and Q, each are —CN or —COO-alkyl. X— is an anion.
