Technical field
The present invention relates to a kind of inorganic-organic compound solution type electrochromic material and device and preparation method, belong to electrochromic material and devices field.
Technical background
Along with the information age today develop rapidly, in the research of the flat-panel monitor of pursuing ultra-thin, reduce power consumption, electrochromic display device has low driving voltage, super contrast gradient clearly, broad visual angle and superior memory effect become the research focus of new display and e-book and electronic newspaper.Add that to the serious day by day energy and the attention of environmental problem, national governments have dropped into great amount of manpower and financial resources are carried out the research and development of electrochromic material and device.
Electrochromic material can be divided into two big classes, and a class is inorganic off-color material, and is modal as MoO
3, V
2O
5, NiO
2, WO
3Or the like.But, for this class electrochromic material, reach practical requirement in order to make its coloration efficiency, must make the ion of injection and electronics be deep into the sull body phase material, its variable color is longer switching time as a result.In addition, the preparation of this type oxide film is had relatively high expectations, should not be too high as Tc, and crystal formation needs strict control.So this class material can not be as MATERIALS FOR DISPLAY.
Another kind of is the organic electrochromic material, by the gain and loss generation oxidation-reduction reaction of electronics, thereby realize painted and fade reversible change.Compare with inorganic electrochromic material, the organic electrochromic material has following several main advantage: the first, and organic electrochromic material variable color speed is very fast, can reach femtosecond; The second, the organic electrochromic material is painted and the contrast gradient of fading is very high, and simultaneously, different gray scales can realize by the size of extra electric field.This just means that the organic electrochromic material has superiority aspect ultra thin device; The 3rd, organic electrochromic material driving voltage is very low, saves the energy; Simultaneously, even after the outage, also keep color changeable effect, has memory effect.
Therefore, people adopt inorganic thin film as photochromic layer usually, or use organic off-color material to prepare electrochromic device as photochromic layer.But up to now, inorganic-organic composite electrochromic material and device yet there are no report.
Summary of the invention

+ 4Solution.This inorganic titanium ion solution is transparent faint yellow.
Organic off-color material mainly is all kinds of straight chain purpurines, as methyl viologen, and ethyl purpurine etc.; And all kinds of purpurine polymkeric substance, as gathering ethyl purpurine etc.They are dissolved in the inorganic titanium ion solution in accordance with the appropriate ratio, just can obtain the compound variable color solution of organic and inorganic.This solution is clear, colorless.
In order to improve coloration efficiency and time of response, the ratio by titanium ion and straight chain purpurine or purpurine polymer molecule realizes.The mole ratio range of general titanium ion and straight chain purpurine or purpurine polymkeric substance is 1: 50-10: between 1.
Organic and inorganic compound solution type electrochromic material of the present invention, its painted and reaction mechanism that fade be organic and the contention of inorganics for electronics on, with methyl viologen and Ti
+ 4System be example, when impressed current, following reaction takes place:
MV
2+(colourless)+e → MV
+(blueness) (1)
When external voltage removed, following reaction took place:
Ti
+ 4+ MV
+(blueness) → Ti
+ 3+ MV
2+(colourless) (2)
