Long-range electron transfer reactions have attracted attention relative to the initial stages of photosynthesis, and special interest has been focused on the design of noncovalently assembled donor-acceptor arrays. Dendrimers with spatially isolated porphyrin cores are potential motifs for investigating such long-range electron transfer reactions [12],... 

The remainder of this section considers several experimental studies of reactions to which the Smoluchowski theory of diffusion-controlled chemical reaction rates may be applied. These are fluorescence quenching of aromatic molecules by the heavy atom effect or electron transfer, reactions of the solvated electron with oxidants (where no longe-range transfer is implicated), the recombination of photolytically generated radicals and the reaction of carbon monoxide with microperoxidase.

Examples of photoredox processes belonging to each of the above groups are given in Table 4. The first three types of photoredox processes (a, b, c) are mostly intracomplex monomolecular reactions (photoredox additions are bimolecular processes) which usually do not occur when a complex is in its ground state. Photoinduced long-range electron transfer reactions can be understood as a boundary between outer-sphere processes (due to a great distance between the reaction sites) and inner-sphere ones (they are, in fact, realized in one molecule). 

Long-range electron-transfer reactions have been investigated in two main groups of metallotetrapyrroles. Natural and synthetic Mg(II) and Zn(II) com-... 

Many other papers on long-range electron transfer between two reactive sites of modified proteins were published [270-288] after the above mentioned pioneering works. Most of them dealt with photoinduced electron tunneling from triplet states of closed shell Mg(II) and Zn(II) porphyrins to Fe(III) or Ru(III). In agreement with the prediction of Marcus theory the rate constants for the majority of these intraprotein electron transfer reactions were found to increase as the free energy of reaction decreased. However for one of the reactions disagreement with this theory was observed [285],...
