摘要： As an example of an EC element in which vertical color separation is suppressed, the present disclosure provides an EC element including a pair of electrodes, a solvent, an anodic EC compound, and a cathodic EC compound. In the EC element, the difference between a solvation free energy of an oxidized form of the anodic EC compound in water and a solvation free energy of the oxidized form in octanol is 35 kcal/mol or more, and the cathodic EC compound has a substituent containing any one element selected from halogens, sulfur, boron, phosphorus, and silicon.

摘要： An organic compound that absorbs light of a wavelength range from 450 nm to 580 nm in a reduction state and is colored and that is superior in high-temperature drive durability and that is expressed by the following formula [1].
Z1 and Z2 each represent a substituent. R11 to R18 each represent a hydrogen atom or a substituent. R12 and R13 are optionally bound to each other to form a ring. R21 and R22 each represent a hydrogen atom or a substituent. X− represents an anion, and n is an integer greater than or equal to 1. When n is 2 or greater, two or more X−s are the same or different from each other.-

摘要： An electrochromic device according to the present disclosure includes an electrochromic element that includes a first electrode, a second electrode, and an electrochromic layer disposed between the first electrode and the second electrode. The electrochromic layer contains an anodic electrochromic compound and an oxidizable substance. The oxidizable substance is a substance which substantially does not undergo a color change due to oxidation and whose oxidant is not reduced. An oxidation reaction of the oxidizable substance is less likely to occur than an oxidation reaction of the anodic electrochromic compound. A controller is configured to control oxidation of the oxidizable substance based on a charge balance of the electrochromic element.

In the above formula (1), R11 to R15 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom provided that at least one of R11, R13, and R15 represents the alkoxy group or the aryloxy group; and R11 to R15 may form a ring structure therebetween. R5 and R6 each independently represent an alkyl group, an aryl group, or an aralkyl group. In addition, R21 to R24 each independently represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, an aralkyl group, an acyl group, or a halogen atom and may form a ring structure therebetween. The above groups except the acyl group may be substituted when necessary.
