Vectorial photoinduced electron transfer (PET) across bilayer lipid and surfactant membranes provides a unique opportunity for the spatial separation of photochemically generated oxidants and reductants. In this chapter a review is given of the data on vectorial PET across the membranes of vesicles and planar bilayer membranes. The key steps that determine the efficiency of PET across membranes are...
Although the transfer of an electron is an elementary chemical event, its consequence on the reactivity of the reagents involved in the exchange is profound, inverting the normal electron demand of each participant. Photoinduced electron transfer provides a sensitive probe for excited state dynamics and the influence of the environment of the excited molecule on the course of both the primary photoinduced...
This review highlights recent studies of synthetic, covalently linked multicomponent molecular devices which mimic aspects of photosynthetic electron transfer. After an introduction to the topic, some of the salient features of natural bacterial photosynthetic reaction centers are described. Elementary electron transfer theory is briefly discussed in order to provide a framework for the discussion...
Artificial photosynthetic devices provide a means for the use of solar light in generating fuel materials and valuable chemicals and for the removal of environmental pollutants. Control of photosensitized electron transfer reactions and development of catalysts for utilizations of the intermediate electron transfer products are essential aspects in designing artificial photosynthetic systems. Homogeneous...
Radical ion pairs play an important role in photoinduced electron transfer (PET) processes. Several types of them may exist and it will be shown in this article that contact ion pairs (CIPs) and solvent-separated ion pairs (SSIPs) can be differentiated by various experimental methods. Moreover, their controlled formation facilitates the control of chemical reactions. Although this review is by no...
