Time-of-flight SIMS was used to study monolayers of the siloxane terminated porphyrin Zn-TESP (C67H75N5O5SiZn) attached to magnesium oxide (MgO) substrates in a silanisation reaction. Time-of-flight SIMS spectra show dependence of the coverage on the preparation temperature. The fragmentation pattern of the porphyrin suggests a strong bond formation to MgO, as was previously reported for SiO2. No signal of physisorbed porphyrin—as previously described for TiO2—could be detected, indicating chemisorbed species under all investigated preparation conditions.
