32. 0 are the excited-state lifetimes of the compound containing the quencher subunit and of the model compound, respectively, obtained from transient absorption and/or luminescence decays.

34. The transient absorption decay of 7 also exhibits a shorter lived, minor component (τ = 30 ps). The origin of this minor component is not discussed here.

39. One of the referees pointed out that, since the energy transfer in the antenna is ultrafast, up-hill hopping in the reverse direction could occur on a timescale similar to that of the observed quenching. That is, charge separation does not have to be remote, but could occur via transient, reversible hopping to the higher energy chromophore attached to the TTF donor. Similarly, recombination could occur via transient hole hopping. This of course would affect the discussion on forward/backward rates. We agree with the referee that this hypothesis cannot be excluded, but in the absence of clear-cut evidence we prefer to maintain our discussion as presented in the main text. In any case, this mechanistic issue does not alter our conclusions.
40. Multicomponent metal-based species in which the light absorbed by some component is transferred to a different subunit where it is used to drive a chemical reaction have been reported. See, for example: S. M. Molnar, G. Nallas, J. S. Bridgewater, K. J. Brewer, J. Am. Chem, Soc. 1994, 116, 5206. However, in the reported systems there was no electron-donor/acceptor group acting as a charge-separation unit.
41. 1 under the same reaction conditions led to the same final products. The trans isomer isomerizes to the cis isomer under the conditions used for the preparation of the metal complexes.
