All in a twist : The largest cucurbit[ n ]uril, namely tQ[14] (see picture; colors indicate sides of the molecule) contains 14 normal glycoluril units linked by 28 methylene bridges. However, it contains a 360° twist. As a consequence, it does not have a normal cavity like the most cucurbit[ n ]urils, and instead has a folded, figure‐of‐eight conformation.
