Chlorophyll-water interaction during oxygen photoevolution at the octane-water interface

Abstract The interaction between water and chlorophyll a dissolved in octane has been studied. Factors governing the formation of the hydrated chlorophyll oligomer with the absorption maximum at 742 nm have been identified. It has been revealed that the water photooxidation reaction sensitized by chlorophyll absorbed at the interface requires the presence of water in the octane phase during self-assemblage of the catalytic complex responsible for the reaction.
