SYNTHESIS AND PHOTOCHEMICAL PROPERTIES OF PORPHYRIN-QUINONE COMPOUNDS

The results of studies on the synthesis of porphyrin-quinone compounds and investigation of their photochemical properties are summarized. E ffects of various factors (the redox potential, the distance between d onor and acceptor moieties, their spatial orientation, the free energy of the reaction, and solvents) on the photoinduced electron transfer in these model systems are discussed. The dyad and triad model systems have been compared. The possibility of using these systems for modeli ng the primary steps of photosynthesis is discussed.
