Random ensembles of femtolitre‐volume droplets containing redox active, photosensitive compounds immobilised on an electrode substrate permit photoelectrochemical studies within femtometric environments. Two chemical systems are described; the first is the N,N,N′,N′ ‐tetrahexyl‐ para ‐phenylenediamine redox‐catalysed photochemical debromination of the anaesthetic reagent halothane; the second is the photoinduced electron transfer from excited chlorophyll a to vitamin K 1 , which has possible potential in the development of solar cells based on photosynthesis.
