Electron transfer between a lutetium bisphthalocyanine and FeIII/II across liquid|liquid interfaces between water and dichlorohexane or nitrobenzene; influence of coupling with ion transfer

► Electron transfer between hexacyanoferrates and a lutetium bisphthalocyanine at liquid/liquid interfaces. ► The LuIII bisphthalocyanine presents over ferrocene the advantage to also be reducible. ► The sandwich-like complex is much less soluble in water than ferrocene and also much more stable. ► The electron exchange and coupling with ion transfers was studied by voltammetry at microinterfaces and spectrophotometry.
