Abstract

Knots and ravels are complicated molecular forms and topologies that can be made with relative ease using noncovalent interactions. The orthogonal arrangement of molecular fragments, leading to the formation of “entanglements,” can be promoted by their coordination to metal ions as well as by hydrogen bonding between amides in a suitably rigid arrangement, or the perpendicular stacking of aromatic rings. In the area of nanometer-scale science, the amazing achievements reached in the formation of knotted structures based on DNA provide inspiration and challenging benchmarks for purely synthetic systems. The resolution of the molecular knots into their enantiomers — topological enantiomers — has been achieved, although the full potential of the compounds as materials for any purpose awaits exploitation.
