Mmm, doughnuts! Six calix[4]arene molecules self‐assemble into a large hexameric torus‐shaped structure through hydrogen bonds (see picture; Br yellow, O red, C gray, H white). The doughnut assembly shows a noteworthy structural similarity to cucurbit[6]uril in the solid state and therefore may be viewed as a noncovalent analogue.
