Tidskriftsartikel (refereegranskat)abstract
- The early stages of interface formation between iron and a three-ring model molecule (trimer) of emeraldine base form of polyaniline (EB) were investigated using theoretical (DFT) and experimental (XPS) methods: Iron atoms were sputter-deposited in ultra high vacuum onto thin oligomer films, with X-ray photoelectron spectroscopy (XPS) core level spectra taken after each deposition. Similar studies were carried out for Fe sputter-deposited on EB polymer films as well. Based on the chemical shifts of the core level peaks and the theoretical results, iron was determined to donate charge (e(-)) into the trimer and EB films. The reverse case where thin films of trimer and EB were deposited on iron also was studied. The C(1s) core level shake up spectra show that the pi-electronic structure is modified for trimer and EB coatings on iron as compared to coatings on gold. (C) 2003 American Chemical Society.
