Electrochromic material and a method for producing the same

摘要

An electrochromic material containing a π-electron based conjugated polymer that changes from a desired color developed state to a decolored state, and a method for producing the electrochromic material, are provided. The electrochromic material contains aπ-electron based conjugated polymer as shown in chemical formula (1). In formula (1),;
each X is any one selected from —S—, —O—, —Se— and —Te—; each Y is any one selected from a hydrogen atom and an organic group having 1 to 20 carbon atoms; W is an arylene group or divalent heteroaromatic ring group; and n is a number of 2 to 1,000. Repetition of this structure forms a structure of random copolymers, graft copolymers, block copolymers and/or dendrimers.
