Entangling strands in a well-ordered manner can produce useful effects, from shoelaces and
fishing nets to brown paper packages tied up with strings. At the nanoscale, non-crystalline …

Supramolecular functional materials represent an emerging class of materials that have
been governed by the supramolecular chemistry of self-assembled molecules. Such high …

Three-dimensional (3D) triply interlocked catenanes are a family of chemical topologies that
consist of two identical, mechanically interlocked coordination cage components with …

Catenanes composed of two achiral rings that are oriented (Cnh symmetry) because of the
sequence of atoms they contain are referred to as topologically chiral. Here, we present the …

Artificial molecular machines (AMMs) have profoundly enhanced scientists' capability to
manipulate the relative movements of components within molecules. Mechanically …

An enantiopure ligand with four bidentate metal-binding sites and four (S)-carbon
stereocenters self-assembles with octahedral ZnII or CoII to produce O-symmetric M8L6 …

Controlling sophisticated motion by molecular motors is a major goal on the road to future
actuators and soft robotics. Taking inspiration from biological motility and mechanical …

Self‐assembly of host molecules in aqueous media via metal–ligand coordination is well
developed. However, the preparation of purely covalent counterparts in water has remained …

Recent developments in artificial molecular machines have enabled precisely controlled
molecular motion, which allows several distinct mechanical operations at the nanoscale …

From being an aesthetic molecular object to a building block for the construction of
molecular machines, catenanes and related mechanically interlocked molecules (MIMs) …
