This Microreview concentrates on synthetic issues regarding shape‐persistent cycles whose diameters range from a bit more than 1 nm up to the presently largest representative with approximately 5 nm. Its goal is to provide an overall feasibility picture and give those, who want to enter this field, some guidelines. An unambiguous structural characterization of these huge molecules is not always an easy task and some related problems will therefore also be discussed. The Microreview is mainly concerned with cycle formation itself and not so much precursor synthesis. Additionally, it places some emphasis on what has been achieved with these intriguing compounds applicationwise and what future they may have. Because of the wealth of material available, a few, clearly stated, yet to some extent artifical restrictions in the selection of cycles had to be applied.
