The present invention relates to an electrochromic material that electrochemically develops and fades color or exhibits a color change. The figure is a sectional view showing an electrochromic display element, in which two transparent substrates 10 made of glass plates or the like are sealed together with a sealing material 11 such as epoxy resin. On one transparent substrate 10,
A display electrode 12 made of In 2 O 3 or SnO 2 is formed in a predetermined pattern. An electrolytic solution 13 consisting of a supporting electrolyte and a solvent is sealed between the two transparent substrates 10. When the electrochromic material is viologen or a compound similar to styryl, this electrochromic material is used as the electrolytic solution 13. It is used by dissolving it in a solvent. If the electrochromic material is a solid film such as WO 3 , display electrode 1
2 has a two-layer structure in which a WO 3 film is formed on a transparent electrode. A counter electrode 14 with a large area is formed on the other transparent substrate 10. As described above, electrochromic materials that are well known today include WO 3 as an inorganic material and viologen as an organic material. In the case of WO 3 and viologen, when coloring or decoloring electrochemically, it is necessary to add or remove ions from the electrochromic material, which results in high power consumption and short display life. It was short. Further, in the case of WO 3 , unless various metal oxides, complexes, and metals such as gold and platinum were used as the counter electrode, the oxidation ring reaction did not occur well and the display characteristics did not improve. Furthermore, WO 3 and viologen can only produce one color, and are not suitable for producing multiple colors. The present invention was made in view of the above problems, and by using a basic material represented by the general formula X-A=CH-Y, power consumption is low, display life is long, and multicolor is possible. The object of the present invention is to provide an electrochromic material that has good contrast and can be used as a display element at low cost. An embodiment of the present invention will be described below. The basic material of the electrochromic display material of the present invention is represented by the following general formula. General formula X-

Styryl type pigments as shown below
An electrochromic solution was prepared by dissolving tetrabutylammonium uperchlorate as a supporting electrolyte in acetonitrile at a concentration of 0.1 M/l and 0.2 M/l. The initial color of this solution is pale yellow. In the display element shown in the figure, a display electrode 12 and a counter electrode 14
When 0.8 to 1.5 V was applied between them so that the display electrode 12 became positive, a red color was observed. When the polarity of the voltage was reversed, it returned to its original yellow color. This yellow←→
When repeating the red color at a voltage of 1.2V with a cycle of 2 seconds, it was found that the red color could be repeated more than 10 6 times. The power consumption required for color development was found to be several + μW/cm 2 . The transparent electrode used was In2O3 . [Example 2] A solution of 0.05 M/l of the structure shown below as a dye and 0.2 M/l of tetrabutylammonium tetrafluoroboronate as a supporting electrolyte in acetonitrile was used as an electrochromic solution. (Japan Photosensitive Color Research Institute, trade name G-146) As in Example 1, this solution also electrochemically showed a color change from yellow to red. It appears that red coloring is achieved by applying 0.8 to 1.5 V to the display electrode 12 and the counter electrode 14 so that the display electrode 12 becomes positive. It was confirmed that the number of repetitions of yellow←→red was more than 106 times. As shown above, the electrochromic material of the present invention has low power consumption, the number of color change cycles is as long as 10 6 times, and the cost of display elements can be reduced, making it a highly useful material. be.
