A composite containing a liposome and a lipophilic ruthenium complex was synthesized to regulate an O 2 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 O 2 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. An O 2 evolution catalyst system based on liposomes and lipophilic Ru( ii ) complexes was fabricated with regulating the surrounding environment of reaction centre.
