A 10~11-Fold Range of Solvent Dynamics Control of Heterogeneous Electron Transfers of Cobalt(III/II)- tris(bipyridine)

摘要

Finally, because the Co(II/I) couple's homogeneous electron transfer rate constants in these same polyether-tailed cobalt bipyridine complex melts are both faster and independent of polyether chain length, we can infer that the Co(III/II) rates in Figure 1 are unaffected by distance-related tunneling barriers Imposed by the polyether shells around the complexes. At the Same time, underscoring our incomplete understanding of Electron transfer self-exchange rates in semisolid media, we Should point out the somewhat surprising insensitivity of the Co(II/I) reaction rate constant to values of D_PHYS.
