    • Note that this calculation provides a rough estimate as analysis was only possible on the compounds that were isolable following potassium cyanide treatment of the nanoparticles and assignments were made based on our limited knowledge of the identities of the compounds. Mechanistic studies on the nucleophilic attack on more electron-rich Fischer carbenes suggest that complete dissociation of the organic ligands from the metal under these conditions may be unlikely. See, for instance: Bernasconi, C. F. Chem. Soc. Rev. 1997, 26, 299-307. Thus, efforts to more accurately quantify the exchange reactions are underway

    • The term superexchange usually refers to bridge-mediated ET in which the intermediate states provide an effective increase in the donor-acceptor nonadiabatic electronic coupling (or termed transfer integral) rather than actual populated sites for stepwise electron hopping. Within this picture, the unoccupied bridge states are higher in energy than that of the donor/acceptor for electron transfer or the occupied bridge states are lower in energy than that of the donor/accepter for hole transfer. The characteristic of superexchange ET through semiconductors/insulators is the drastic decay of ET rates over the distance that the electron travels, i.e, the effective electronic coupling or conductance decays exponentially versus the ET distance. It should also be mentioned that in the superexchange mechanism the donor-acceptor coupling is usually a combination of through-bond (nearest-neighbor tunneling) and through-space (long distance) interactions. For more detailed discussion, see: Ratn
