Interlocked cyclic compounds?

Question

Being new to chemistry, there maybe some properties I couldn't understand fully. One of them being cyclic compounds. One particular question about this is, whether these cyclic compounds, say benzene rings 'link' in-between one another like a chain. Having one molecule chain of one benzene molecule, go through the center of another, before closing back up as a ring. Unfortunately, I couldn't seem to find any term describing it for further research.

Answer 1

Benzene is pretty unlikely to do it because of all the space required by the pi electrons. Nonetheless, it can still be done. Cyclic compounds can often be mixed with other rings or on chains. This is budding in research because it will be the main design in a molecular motor, such as in a nano-robot/machine.

You can just call them interlocked molecules. But if they are both [relatively] large cyclic compounds, the term is catenane. A catenane is defined as "a molecule containing two or more intertwined rings."
