Challenging Characterisation: Precise determination of the conformation and electronic properties of haemoporphyrin–metal interfaces are important for device characterisation. The authors show that metalloporphyrins lie more planar on the substrate than the metal‐free porphyrins, which are less tilted with respect to the surface normal direction (see sum‐frequency generation, SFG, spectra).
