Photoinduced electron transfer

Simple d1-d9 transition metal complexes

edit
  • Colour arises from d-d transitions
  • Excited states very short lived
  • Decay by internal conversion, a sequence of complicated steps that convert electronic energy into thermal energy

Mixed-valence compounds

edit

Magnetite

edit
  • Magnetite, Fe3O4 is a mixed valence iron oxide, containing both Fe2+ and Fe3+
  • Its electrical conductivity is a million times greater than isovalent Fe2O3, which contains only Fe3+

Prussian blue

edit
  • Prussian blue, , also contains both Fe2+ and Fe3+
  • A three-dimensional coordination network of octahedral low-spin {FeII(CN)6} and high-spin {FeIII(NC)6} nodes
  • Its intense blue colour is due to electron transfer from Fe2+ to Fe3+
