Directionality is key for the functionality of molecular machines, which is often achieved by
built-in structural chiralities. Here, we present a scanning tunneling microscopy study of …

Induction of chirality in planar adsorbates by hydrogenation of phthalocyanine molecules on
a gold surface is demonstrated. This process merely lowers the molecular symmetry from 4 …

Scanning tunneling microscopy (STM) and density functional theory (DFT) were used to
study the tautomerization reaction of an H2Pc molecule adsorbed on a Ag (100) surface …

Surface-supported molecular motors are nanomechanical devices of particular interest in
terms of future nanoscale applications. However, the molecular motors realized so far …

Molecular motors have chemical properties that enable unidirectional motion, thus breaking
microscopic reversibility. They are well studied in solution, but much less is known regarding …

Molecular motors are nanoscale machines that convert external energies into controlled
mechanical movements. In supramolecular motors, the rotator and stator are held together …

Understanding the directed motion of a single molecule on surfaces is not only important in
the well-established field of heterogeneous catalysis but also for the design of artificial …

Molecular chirality on surfaces has been widely explored, both for intrinsically chiral
molecules and for prochiral molecules that become chiral upon adsorption due to the …

Molecular electronics where single molecules perform basic functionalities of digital circuits
is a fascinating concept that one day may augment or even replace nowadays …

Quantum tunneling of hydrogen atoms (or protons) plays a crucial role in many chemical
and biological reactions. Although tunneling of a single particle has been examined …
