We have successfully synthesized a Li salt, which is constructed by [Ni(dmit)₂]^– and supramolecular cations consisting of Li⁺ and crown ethers. The Li salt shows a solid state ion-exchange property in which Li⁺ ions are completely exchanged with metal ions when immersed in an aqueous solution containing the metal ions. In this study, we aimed to achieve hole doping of the [Ni(dmit)₂]^– layer by inducing electron transfer from [Ni(dmit)₂]^– molecules to the electron-accepting Cu²⁺, introduced into Li salt through the solid state ion-exchange property.
