Chiral C3-symmetric molecule assembly enabling topological nanotoroid, fused nanotoroid, and nanocatenane Despite extensive studies on chiral self-assembled nanostructures, constructing topological nanostructures like toroidal assemblies and their higher-order fused/catenated derivatives remains challenging. Here, a hierarchical assembly strategy using C3-symmetric benzene-1,3,5-tricarboxamide enables topological evolution into discrete nanotoroids, fused super-nanotoroids (up to 21 units), and nano-[2]catenanes. These chiral nanotopologies template achiral fluorophores to induce bright, circularly polarized luminescence across the visible range, revealing the synergy between chiral hierarchy and topological architectures in supramolecular self-assembly. http://dlvr.it/TLx9Jr
