(JA) エレクトロクロミック材料
Abstract: front page image
(EN)Disclosed is an electrochromic polymer compound which is composed of a hyperbranched polymer having a moiety exhibiting electrochromic characteristics ascribed to a quaternary pyridinium salt, terephthalic acid diester or biphenyl-4,4'-diester structure.  A varnish and a thin film structure each obtained from the polymer compound, and an electrochromic device are also disclosed.  The electrochromic material has high response speed, while having high coloring efficiency and excellent solubility in various solvents.  In addition, the electrochromic material has excellent repetition stability and can be used for a long time.
(FR)La présente invention concerne un composé polymère électrochrome qui est composé d'un polymère hyper-ramifié présentant les caractéristiques habituelles d'électrochromie d'une structure de sel de pyridinium quaternaire, de diester d'acide téréphtalique ou de diphényl-4,4'-diester. L'invention concerne également, d'une part un vernis et une structure de film mince s'obtenant tous les deux à partir du composé polymère, et d'autre part un dispositif électrochrome. Cette matière électrochrome se distingue par sa vitesse de réponse élevée, son pouvoir colorant élevé, et son excellente solubilité dans divers solvants. En outre, cette matière électrochrome s'avère très stable aux répétitions et sa longue durée de vie utile.
