Regulation of a cerium(IV)-driven O₂ evolution reaction using composites of liposome and lipophilic ruthenium complexes

A composite containing a liposome and a lipophilic ruthenium complex was synthesized to regulate an O₂ evolution reaction using cerium(IV) ammonium nitrate as an oxidizing reagent. We found that the surrounding environment of the reaction centre is an important factor for controlling the O₂ evolution catalytic reaction. We successfully regulated the reaction activity using the linker length of the lipophilic ligand and using the head groups of the phospholipid component.
