Abstract: | Nanosupramolecular assemblies with controlled topological features have inventive applications in fundamental studies and material manufacturing. Herein, a variety of morphologically interesting aggregates have been constructed using the supramolecular modulation with bipyridinium‐modified diphenylalanine derivative (BP‐FF). Benefiting from the high binding affinity of bipyridinium group with four different macrocyclic receptors, namely cucurbit7]uril, cucurbit8]uril, pillar5]arene, and tetrasulfonated crown ether, we have succeeded in tuning the topological aggregates of BP‐FF from fine nanofibers to nanorods, octahedron‐like nanostructure, helical nanowires, and rectangular nanosheets without any tedious chemical modification. This supramolecular approach may provide us a powerful method to construct well‐defined nanostructures with different morphologies that can be conveniently controlled by facile host–guest interactions. |
