The design of stable redox active liposomes where the organometallic electroactive pendent was covalently bound to the phospholipid headgroup through a phospholipase D (PLD)-catalyzed transphosphatidylation reaction between a choline-bearing phospholipid and a primary alcohol containing a ferrocene derivative is reported. The functionalization of a liposome surface with this organometallic redox phospholipid allowed the study of membrane-bound electrochemical reactions, which are important in the design of redox-sensitive liposome delivery systems.
