The social self‐sorting supramolecular assembly is described by non‐covalent interactions among four organic components. Toward this goal, a series of self‐sorting systems have been investigated by mixing two or three different compounds; naphthyl‐bridged bis(α‐cyclodextrin), N , N ′‐dioctyl‐4,4′‐bipyridinium, 2,6‐dihydroxynaphthalene, and cucurbit[8]uril. The influence of alkyl chains of viologen derivatives and the binding abilities of these systems have also been studied. Their integrative self‐sorting led to the exclusive formation of the purple supramolecular heterowheel polypseudorotaxane. The heterowheel polypseudorotaxane is a thermodynamically stable self‐sorted product, and consists of two different macrocycles with three sorts of different non‐covalent interactions. Its structure was established by NMR spectroscopy and UV/Vis absorption spectroscopy, transmission electron microscopy (TEM), atomic force microscopy (AFM), dynamic light‐scattering (DLS), diffusion‐ordered spectroscopy (DOSY), and viscosity measurements.
