Controllable construction of diversiform topological morphologies through supramolecular self-assembly on the basis single building block is vital importance, but still remains a big challenge. Herein, bola-type supra-amphiphile, namely DAdDMA@2β-CD, rationally designed and successfully prepared by typical host-guest binding β-cyclodextrin units with an aggregation-induced emission (AIE)-active scaffold DAdDMA. Self-assembling investigation reveals that several self-assembled DAdDMA@2β-CD including leaf-like lamellar structure, nanoribbons, vesicles, nanofibers, helical toroids, can be straightforwardly fabricated simply manipulating self-assembling solvent proportioning and/or temperature. To best knowledge, this presented protocol probably holds most types morphology alterations using entity. Moreover, developed structure performs well in mimicking light-harvesting antenna system incorporating Förster resonance energy transfer acceptor, providing up to 94.2% efficiency.
