The “nanolimpiadâ€, as the complex structure of self-assembled links has been named, looks like the five Olympic Rings and may become the source of new polymeric materials with innovative properties. A collaboration of research groups from Japan (Chiba University), Italy (Politecnico di Torino), Switzerland (SUPSI) and the UK (Keele University, the Diamond Light Source &the ISIS Pulsed Neutron and Muon Source) has succeeded in developing and studying supramolecular poly-catenanes: hierarchical structures composed of mechanically interlocked self-assembled rings, made solely from one elementary molecular ingredient.
