Stereoselective energy transfer reaction

One of the most important issues to be investigated is to clarify the stereoselective electron transfer reaction and the energy transfer reaction from the viewpoint of physical chemistry. For instance, the parameters of Marcus theory have not been reported yet for the stereoselective electron transfer reaction. 

In summary, the stereoselectivity was certainly observed in the photoin-duced electron transfer reactions of chiral ruthenium(II) complexes with chiral viologen and Co(III) complexes. However, not only the photoinduced electron transfer reaction but also the charge separation in the encounter complex and the reverse reaction between the ruthenium(III) complex and Co(acac)2 + acac participate in the stereoselection. In the reactions between the ruthenium(II) and Co(III) complexes, the energy transfer also contributes to the quenching reaction, which makes difficult the observation of stereoselectivity in the quenching reaction.
