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.

Abstract: The present disclosure provides an organic compound that has a mother skeleton with a fused-ring structure, an electron-withdrawing group bonded to the mother skeleton, and an electron-donating group bonded to the mother skeleton, wherein the electron-withdrawing group is bonded at a position satisfying the following relationship in the mother skeleton. Σ C H > Σ C L
(C H : 2PZ atomic orbital coefficient of a carbon at a substitution site in the HOMO of the mother skeleton)
(C L : 2PZ atomic orbital coefficient of the carbon at the substitution site in the LUMO of the mother skeleton)

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.
