Common Mistakes When Using “catenane”
- Mispronouncing it as /keɪˈtiːneɪn/ (like 'caffeine').

- Confusing it with 'rotaxane' (a ring threaded on a dumbbell-shaped molecule).
FAQ
Frequently Asked Questions
It is considered a single molecule because the rings are mechanically interlocked and cannot be separated without breaking a covalent bond. However, the sub-components (the individual rings) are not covalently bonded to each other.
A catenane consists of two or more interlocked rings (like chain links). A rotaxane consists of a linear 'axle' molecule threaded through a ring, with bulky 'stoppers' on the ends of the axle to prevent the ring from slipping off.
Yes, but they are extremely rare. Some circular DNA molecules can become interlocked, forming catenanes, which are intermediates in DNA replication and recombination processes.
They are studied as components for molecular electronics, as switches and shuttles in molecular machines, and as models for understanding complex molecular motion and topology.
A molecule consisting of two or more interlocked macrocyclic rings, like links in a chain, with no covalent bonds between them.
