27. 60 partner experiences negligible changes upon reduction. However, solvent reorganization involving the Ir(iii) moiety is expected to be significant, particularly in the presence of moderate driving force, as in this case (-0.40 eV, see above). In other words, the moderately exergonic electron transfer from the Ir-based MLCT state to fullerene should be inefficient at 77 K
28. Note that such an assumption does not exclude the possibility that electron transfer can contribute to some extent to the quenching process at r.t
