Abstract

The interface between two immiscible liquids with immobilized photosynthetic pigments can serve as the simplest model of a biological membrane convenient for the investigation of photoprocesses that are accompanied by spatial separation of charges. Oxygen evolution with a quantum efficiency of 10-20% can be seen by illuminating the octane/water interface having hydrated oligomer of chlorophyll a with proton acceptors in octane and electron acceptors in water. Considering the importance of such a model of photosynthetic membranes, in the present communication we have investigated the optical and absorption properties of wet chlorophyll a. The absorption, circular dichroism, and fluorescence properties of chlorophyll a in a non-polar solvent and in thin films were studied. The adsorption isotherms of dry and wet chlorophyll a at octane/water interface were also measured. The difference in adsorption behavior of chlorophyll a dissolved in dry and wet octane is discussed.
