The conductances of molecular model junctions comprising a triazatriangulenium platform with fr9967 or without an ethynyl spacer and an upright Zn-porphyrin are probed with a low-temperature scanning probe microscope.The platform alone is found to be highly conductive.The ethynyl-linked Zn-porphyrin moiety reduces the conductance by three orders of magnitude and leads to an unexpected, non-monotonous variation of the rogue st pro 3 iron force that was measured simultaneously at the tip of the microscope.Density functional theory calculations show that this variation results from an induced tilting of the porphyrin.
