Molecular platforms with multiple anchors were introduced recently to provide robust
coupling between molecular electronic components and metallic electrodes. In this work,
charge transport in tower-shaped single molecule conductors based on tetraphenylmethane
tripod possessing three thiol anchors is investigated by scanning tunneling microscopy break
junction technique. The effect of tripod substitution pattern and number of repeating units in
molecule is addressed. The substitution was found to influence conductance value in early
stages of molecular junction evolution, where tower lays parallel to surface. In late stages, the
charge is transported through principal molecular axis and junction breaks thermally in tilted
configuration.
