Very much so. There are different synthetic methods that could be used to create these so called “catenanes”, from a slapdash wait-and-see process where the starting material is thrown together and by hope and statistics a product comes out of the reaction with two interlocked rings. Otherwise one could build up a reaction with a starting material in a shape that’s conducive to a ring structure then attempt complexation/liganding etc etc finish and close the rings so they interlock. For some interesting reading in self-assembling structures see: Hao Li et al. Quantitative self-assembly of a purely organic three-dimensional catenane in water, Nature Chemistry (2015).
