Abstract:
1. A linear electrochromic polymer material comprising first to Nth bis-terpyridine derivatives (N is an integer of 2 or greater), first to Nth metal ions (N is an integer of 2 or greater) and first to Nth counter anions (N is an integer of 2 or greater), the electrochromic polymer material being represented by the following formula: where M 1 , . . . , M N are first to Nth different metal ions, respectively (N is an integer of 2 or greater); R 1 , . . . , R N are each independently a spacer that contains a carbon atom or a hydrogen atom, or directly links corresponding terpyridyl groups to each other (N is an integer of 2 or greater); R 1 1 , . . . , R 1 N , R 2 1 , . . . , R 2 N , R 3 1 , . . . , R 3 N , R 4 1 , . . . , R 4 N are each independently a hydrogen atom, an aryl group or an alkyl group (N is an integer of 2 or greater); n 1 , . . . , n N are each an integer of 2 or greater indicating the degree of polymerization; and the first to Nth counter anions are identical to, different from, or partly equal to one another.
