The organic/inorganic interface: a study of direct electron transfer

• Porphyrins have become an interesting class of molecules in studies of molecular electronics. They are, however, sensitive to handling procedures and may give different results in electronic or optical properties depending on the method used for coupling or adsorption. We present electronic measurements of a heme porphyrin mounted in a biomolecular structure-an enzyme-and show that a direct electron transfer between the enzyme and the electrode results from a chemical reaction
