High-conductance surface-anchoring of a mechanically flexible platform-based porphyrin complex
The conductances of molecular model junctions comprising a triazatriangulenium platform with or without an ethynyl spacer and amrutharishtam price 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 t
