Ruthenium complex stereoselective photoinduced electron

B. Stereoselective Photoinduced Electron Transfer Reaction of Ruthenium(ll) tris-Bipyridine Complexes... 

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.
