Abstract

original image

To be or not to be chlorinated: When octaethylporphyrin iron(III) chloride (FeOEP[BOND]Cl) molecules are sublimated onto Cu(111) surfaces, two different molecular species are observed through scanning tunneling microscopy, showing either a protrusion or a depression at the center. In combination with van der Waals-corrected density functional calculations, our experiments reveal that one species corresponds to FeOEP[BOND]Cl molecules with the chlorine atom pointing away from the surface, whereas the other species has been dechlorinated.
