Host–guest complexation between pillararene trimer 1 and biviologen 2 was used to fabricate the dynamic supramolecular self-assembly, which exhibits a reversible multidimensional transformation from 0D to 3D upon concentration changes. As a comparison, assemblies built by the complexation between 1,4-dimethoxypillar[5]arene and 2 only show spherical morphology under similar conditions.
