SINGLE-LAYER PARTITIONED ELECTROCHROMIC DEVICE HAVING ELECTROCHROMIC POLYMER MATERIAL Russian patent published in 2012 - IPC G02F1/15 C09K9/02 C08L39/04 

FIELD: physics.

SUBSTANCE: solution contains: (a) non-aqueous solvent; (b) cathode material which is pyridine-containing electrochromic polymer material of Formula 1: Formula 1 , where each Ar group independently denotes a C₆-C₁₀₀ aryl group which contains or does not contain a heteroatom; R₁ is a C₆-C₁₀₀ arylene group which contains or does not contain a heteroatom; R₂ is a C₆-C₁₀₀ arylene group which contains or does not contain a heteroatom, a linear alkyl group or a cyclic alkyl group; X is an anion selected from a group consisting of F^-, Cl^-, Br^- l^-, NO₃ ^-, N(CN)₂ ^-, BF₄ ^-, ClO₄ ^-, RSO₃ ^-, RCOO^-, PF₆ ^- (CF₃)₂PF₄ ^- (CF₃)₃PF₃ ^- (CF₃)₄PF₂ ^- (CF₃)₅PF^-, (CF₃)₆F^-, (CF₃SO₃ ^-)₂, (CF₂CF₂SO₃ ^-)₂, (CF₃SO₃)₂N^- CF₃CF₂(CF₃)₂CO^-, (CF₃SO₂)₂CH^-, (SF₅)₃C^-, (CF₃SO₂)₃C^-CF₃(CF₂)₇SO₃ ^-, CF₃CO₂ ^- and CH₃CO₂ ^-; and n ranges from 2 to 1000; and (c) anode material, which is aniline-based electrochromic material of Formula 4: Formula 4 . The cathode material and anode material is dissolved in non-aqueous solvents. An electrochromic device, a cathode for the electrochromic device and an anode for the electrochromic device are also disclosed.

EFFECT: invention provides excellent cost-effectiveness of the electrochromic device, high drop in optical density and longevity.
