In the context of optimizing charge-separation processes in artificial model systems, meaningful incentives are lent from bacterial photosynthetic reaction centers [1]. Whereas in green or purple bacteria only one photosynthetic unit — PS II — is carrying out the light-to-chemical product conversion, green plants are using two systems — PS I and PS II [2]. Essential to all these systems is a relay of short-range energy/electron transfer reactions, evolving among chlorophyll- and quinone-moieties embedded in a transmembrane protein matrix. Ultimately the product of these cascades is transformation of light into usable chemical energy. The latter governs water cleavage to O2 and reduction of NADP to NADPH, which is used to produce in its final instant sugars from CO2.
