Embodiment Construction

[0041] Below in conjunction with embodiment the present invention is described in further detail.

[0042] Synthesis of color-changing material and preparation of its solution

[0043] 1) Reflux 1.56g (0.01mol) 4,4'-bipyridine and 4.06g (0.02mol) 2,4-dinitrochlorobenzene in 30ml acetonitrile for 24 hours, then cool, filter under vacuum, and dry The resulting solid gave 1-(2,4-dinitrophenyl)-4,4'-bipyridinium chloride (3.82 g). Then 1,1-bis(2,4-dinitrophenyl)-4,4'-bipyridinium chloride (1.46g, 0.004mol) and p-methoxyaniline (0.492g, 0.004mol) in Reflux in ethanol (30ml) for 6 hours, cool, remove ethanol in vacuo, add water (50ml) and stir. The precipitate was filtered, the filtrate was decolorized with activated carbon, and dried in vacuo to give the crude product 1,1-di-p-methoxyphenyl-4,4'-bipyridinium chloride salt, which was recrystallized to give the pure crystalline product (0.98 g) .

[0044] Take out 0.5 g of the obtained product, 1 g of the compound of general stru...

Abstract

The present invention discloses main compound in cathode electroinduced off-color material, characterized in that compound in structure general formula (I) is adopted, relevant electroinduced off color component which is composed by a piece of transparent glass with conductive film and a piece of glass with reflection layer and conductive film, and the two conductive films and frame glue constitute a hollow space; electroinduced off-color material is placed inside the hollow space and characterized in that cathode electroinduced off-color material mainly contains compound in structure general formula (I) which has features like more stable, easy synthesis and low cost, and can be applied on full-automatic anti-dazzle rear-view mirror or intelligent windows.

Description

technical field [0001] The invention relates to a main compound in an electrochromic material and an electrochromic device thereof, which are used in related fields such as automatic anti-glare rearview mirrors and related intelligent windows. Background technique [0002] Electrochromism refers to the phenomenon of reversible changes in the optical properties of materials such as transmission, reflection, and absorption in a certain wavelength range caused by electron transfer of color-changing materials under the action of an electric field. Electrochromic materials have some unique advantages: the optical properties of the material can be continuously adjusted in a wide range, and light modulation can be realized; the working voltage is low, the energy consumption is low, and it is easy to match with integrated circuits; the working temperature range is wide, and it is suitable for large-scale production. According to climate and seasonal changes, the transmittance of sol...
