Abstract

Supramolecular toroids have attracted continuous attention because of their fascinating topological structure and important role in biological systems. However, it still remains a great challenge to construct supramolecular functional toroids and clarify the formation mechanism. Herein, we develop a strategy to prepare supramolecular helical fluorescent nanotoroids by cooperative self-assembly of an amino acid and a dendritic amphiphile (AIE-den-1) with aggregation-induced emission characteristics. Mechanistic investigation on the basis of fluorescence and circular dichroism analyses suggests that the toroid formation can be driven by the interactions of AIE-den-1 with amino acid and goes through a topological morphology transformation from nanofibers to left-handed nanotoroids by means of a twist-fused-loop process.
