Microscopic evidence of the in situ complexation of Fe‐porphyrins is presented. The figure shows the sub‐molecular resolved scanning tunneling microscopy images which document the metalation of 2H‐TPP (central cavity; TPP: tetraphenylporphyrin) with evaporated iron (protrusions are identified as Fe‐TPP). This promising technique enables future surface science investigations of clean iron porphyrin films under ultrahigh vacuum conditions.
