The cleavage of the ubiquitous and abundant molecules H2O, CO2 (or CO32-, respectively) and N-2 is of is of considerable interest. Owing to their stability this splitting should be facilitated by light and may thus be applied for solar energy utilization. Under ambient conditions the direct photocleavage can certainly not be accomplished but assistance by suitable redox-active metal complexes is conceivable. Light absorption should induce charge redistribution between metal and molecules to be split. CT excitation is expected to initiate the generation of redox products in the first photochemical step. Indeed, the redox couples (OsCp2)-Cp-II/(OsCp2)-Cp-IV with Cp = cyclopentadienyl anion, Cu(I)/Cu(II) and (OsN2OsIII)-N-II/Os-VI(N) have been successfully applied to photo cleave H2O, CO32- and N-2, respectively. Future attempts are directed to improve the efficiency of these photoreactions. In particular, the inclusion of such reactions in photocatalytic cycles is a challenging task.
