Title:
Π-ELECTRON CONJUGATED COMPOUND, MANUFACTURING METHOD THEREFOR, AND Π-ELECTRON CONJUGATED POLYMER OBTAINED USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/044470
Kind Code:
A1
Abstract:
Disclosed is a π-electron conjugated polymer that is suitable as an electrochromic material that changes from a desired color-developed state to a decolored state and that has a structural unit represented by general formula (2); further disclosed are a novel compound that is the starting material thereof and a manufacturing method therefor. (2) [In the formula, each X independently represents one selected from a group comprising an oxygen atom, a sulfur atom, and -NH- and -NR1- (wherein R1 is an optionally substituted alkyl group with 1‑20 carbons, or an optionally substituted aryl group with 6‑20 carbons); each Y independently represents an oxygen atom or a sulfur atom; each Z independently represents one selected from a group comprising a hydrogen atom and an optionally substituted organic group with 1‑20 carbons; W is one selected from a group comprising an ethenylene group, an optionally substituted ethenylene group, an optionally substituted arylene group, and an optionally substituted bivalent heteroaromatic ring group; and n is an integer of 2 or higher.]
