abstract = {The part-by-part assembly of functional nanoscale machinery
is a central goal of nanotechnology. With the recent
fabrication of an isolated standing molecule with a scanning
probe microscope, the third dimension perpendicular to the
surface will soon become accessible to molecule-based
construction. Beyond the flatlands of the surface, a wealth
of structures and functionalities is waiting for
exploration, but issues of stability are becoming more
critical. Here, we combine scanning probe experiments with
ab initio potential energy calculations to investigate the
thermal stability of a prototypical standing molecule. We
reveal its generic stabilization mechanism, a fine balance
between covalent and van der Waals interactions including
the latter’s long-range screening by many-body effects,
and find a remarkable agreement between measured and
calculated stabilizing potentials. Beyond their relevance
for the design and construction of three-dimensional
molecular devices at surfaces, our results also indicate
that standing molecules may serve as tunable mechanical
gigahertz oscillators.},
