Abstract

The present invention provides an organic compound represented by the following general formula [1], the organic compound having high solubility in a polar solvent used in an EC device, high transparency in the bleached state and high stability against repetition of an oxidation-reduction reaction.

Claims

1. An organic compound represented by the following general formula [1]:

2. The organic compound according to claim 1, wherein the A₃ is the same substituent as the A₁, and the A₄ is the same substituent as the A₂.

3. The organic compound according to claim 1, wherein at least one of the A₁ to the A₄ is an alkoxy group having 1 or more and 20 or less carbon atoms.

4. The organic compound according to claim 3, wherein the alkoxy group is a methoxy group or an isopropoxy group.

5. The organic compound according to claim 1, wherein the X is an integer of 1 or more and 5 or less.

6. An electrochromic device comprising:

a pair of electrodes; and

an electrochromic layer arranged between the pair of electrodes,

wherein the electrochromic layer contains an electrochromic compound and an electrolyte, and the electrochromic compound is an organic compound according to claim 1.

7. The electrochromic device according to claim 6, wherein the electrochromic layer is a layer comprising a liquid material containing the electrochromic compound and the electrolyte.

8. The electrochromic device according to claim 6, wherein the electrochromic layer further contains a second electrochromic compound which is a material other than the organic compound.

9. The electrochromic device according to claim 8, wherein the second electrochromic compound is a compound having low visible light transmittance in the reduced state.

10. An optical filter comprising an electrochromic device according to claim 6 and an active element connected to the electrochromic device.
