Abstract: 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.

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 difference between a solvation free energy of a reduced form of the cathodic EC compound in propylene carbonate and a solvation free energy of the reduced form in octanol is -35 kcal/mol or less.

Abstract: An organic compound is represented by general formula (1) below:

where X 1 and X 2 are each independently selected from an alkyl group optionally having a substituent, an aryl group optionally having a substituent, and an aralkyl group optionally having a substituent;
R 11 to R 16 are each independently selected from a hydrogen atom, an alkyl group optionally having a substituent, an alkoxy group optionally having a substituent, an aryl group optionally having a substituent, a heterocyclic group optionally having a substituent, and a halogen atom; R 21 and R 22 are each independently selected from a hydrogen atom, an alkyl group optionally having a substituent, an aryl group optionally having a substituent, and an aralkyl group optionally having a substituent; and A 1 - and A 2 - each independently represent a monovalent anion.
