Time‐of‐flight SIMS was used to study monolayers of the siloxane terminated porphyrin Zn‐TESP (C 67 H 75 N 5 O 5 SiZn) 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 SiO 2 . No signal of physisorbed porphyrin—as previously described for TiO 2 —could be detected, indicating chemisorbed species under all investigated preparation conditions.
