Title (EN) BLACK-TO-TRANSMISSIVE ELECTROCHROMIC DEVICE
(FR) DISPOSITIF ÉLECTROCHROME NOIR À TRANSMISSIF
Abstract:
(EN) Disclosed is a redox-complementary electrochromic device exhibiting black-to-transmissive switching, wherein the device comprises an electrochromic layer and a redox-active material layer sandwiched between a transparent first electrode and a transparent secondary electrode, the electrochromic layer comprising an electrochromic Co-based metallo-supramolecular polymer represented by the formula (I), and the redox active material being capable of reacting with the electrochromic material to change the electrochromic material from black state into colorless transmissive state. (In the formula (I), X represents a counter anion, R represents a single bond or a spacer comprising a carbon atom and a hydrogen atom, each of R1 to R4 independently represents a hydrogen atom or a substituent group, and n represents an integer of from 2 to 5000, which indicates a degree of polymerization.)
(FR) La présente invention concerne un dispositif électrochrome complémentaire redox présentant une commutation de noir à transmissif, le dispositif comprenant une couche électrochrome et une couche de matériau actif redox intercalé entre une première électrode transparente et une électrode secondaire transparente, la couche électrochrome comprenant un polymère métallo-supramoléculaire à base de Co électrochrome représenté par la formule (I), et le matériau actif redox étant capable de réagir avec le matériau électrochrome pour changer le matériau électrochrome d'un état noir à un état transmissif incolore. (Dans la formule (I), X représente un contre-anion, R représente une simple liaison ou un espaceur comprenant un atome de carbone et un atome d'hydrogène, chacun de R1 à R4 représente indépendamment un atome d'hydrogène ou un groupe substituant, et n représente un nombre entier de 2 à 5000, qui indique un degré de polymérisation.)
