Essay
Electron transfer is ubiquitous in chemical, physical and biological
systems – the phenomenon is fundamental in natural processes such
as photosynthesis, and in materials science applications. Mixed-valence
dinuclear complexes have received significant attention in electron
transfer studies as the characteristics of their intervalence charge
transfer (IVCT) bands provide a powerful probe of the factors which
govern the barrier to electron transfer. The Franck-Condon factors correspond
to the reorganisational energies within the inner- and outer-sphere
(respectively), the redox asymmetry, is the energy difference between
the two metal-based chromophores, and . E' incorporates spin-orbit coupling
contributions.
Previously, these factors have been probed by the variation of “global”
features of the complexes – such as the identity and coordination
environments of the metal centres, or through variation of properties
of the solvating medium. The work reported in this thesis is the first
to reveal stereochemical effects on the electrochemical, spectral and
IVCT characteristics of a range of di- and tri-nuclear complexes incorporating
the bridging ligands shown in Figure 1 [see
full text from below], and challenges prior assertions that the
inherent stereochemistry of polymetallic assemblies would have no influence
on their physical properties...[full text; pdf
