Provided are a π-electron conjugated polymer having a constitutional unit represented by general formula (2) that is suitable as an electrochromic material that changes from a desired colored state to a decolored state, a new compound that is a raw material of the polymer, and a method for producing the polymer: wherein each X independently represents one selected from the group consisting of an oxygen atom, a sulfur atom, —NH—, and —NR1— (wherein R1 is an optionally substituted alkyl group having 1 to 20 carbon atoms or an optionally substituted aryl group having 6 to 20 carbon atoms); each Y independently represents an oxygen atom or a sulfur atom; each Z independently represents one selected from the group consisting of a hydrogen atom and optionally substituted organic groups having 1 to 20 carbon atoms, and W is one selected from the group consisting of an ethynylene group, an optionally substituted ethenylene group, optionally substituted arylene groups, and optionally substituted divalent heteroaromatic ring groups; and n is an integer of 2 or greater.
提供了一种π-电子共轭聚合物,其具有适用于作为电致变色材料的结构单元,该结构单元由一般式(2)表示,从预期的有色状态变为无色状态,一种作为该聚合物原料的新化合物,以及一种制备该聚合物的方法:其中每个X独立地表示从氧原子、硫原子、—NH—和—NR1—(其中R1是具有1到20个碳原子的可选择取代的烷基基团或具有6到20个碳原子的可选择取代的芳基基团)中选择的一个;每个Y独立地表示氧原子或硫原子;每个Z独立地表示选择自氢原子和具有1到20个碳原子的可选择取代的有机基团的一种;W是选择自乙炔基团、可选择取代的乙烯基团、可选择取代的芳基基团和可选择取代的二价杂环芳基团的一种;n是大于或等于2的整数。
