Abstract
The electronic properties and the molecular orientation of Zn-tetraphenyl-porphyrin films deposited on Si(1 1 1) have been investigated using synchrotron radiation. For the first time we have revealed and assigned the fine structures in the electronic spectra related to the HOMOs and LUMOs states. This is particularly important in order to understand the orbital interactions, the bond formation and the evolution of the electronic properties with oxidation or reduction of the porphyrins in supramolecular donor–acceptor complexes used in photovoltaic devices.
