These processes to maintain the electroneutrality of the droplet of the organic phase are the basis of ion transfer studies . For cation transfer, fullerene C60 , 7,70,8,80tetracyanoquinodimethane (TCNQ) , quinones , iron(III) tetraphenylporphyrin chloride and iodine have been used as redox molecules. For anion transfer, most studies use decamethylferrocene (DMFc) and other ferrocene derivatives , , , . In some cases, Ru-complexes and tetraphenylporphyrinato (TPP) metal complexes (MnTPP+, FeTPP+, CoTPP) , are used. Lutetium bis(tetratert-butylphthalocyanine) and 2,2-diphenyl-1-picrylhydrazyl have been used as redox probes for both anion and cation transfer. Since the oxidation (or reduction) of the redox molecule is connected with the transfer of an ion across the liquid-liquid interface, two characteristic effects can be observed in threephase electrode experiments: a shift of the oxidation peak potential to more positive values the more hydrophilic the transferred anion is, and a dependence of the ion concentration on the peak potential. In general, the more hydrophilic the ionic species, the higher potential must be applied to transfer it to the organic phase. To quantitatively characterize this effect, the standard transfer potential of the anion ∆ aq org 𝜑 An - 0 is used. It is one of the parts in the Nernst-like equation (1) describing the ion transfer process:
