Tailoring multi-dimensional hierarchical self-assembly of metallacages through balancing non-covalent interactions.

ABSTRACT: Despite advances in non-covalent interactions and complex self-assembly, precise control of multi-dimensional hierarchical self-assembly (HSA) from the molecular level to larger scales remains challenging. Herein, we designed and synthesized two rigid tetratopic ligands with multiple preset driving forces, and assembled them with Zn(ii) ions to obtain metallacages SC6 and SC12. Through balancing multiple non-covalent interactions, including metal-organic coordination, hydrophobic, and π-π interactions, SC6 can hierarchically self-assemble driven by a poor solvent, from one-dimensional nanowires to super-helical nanostructures via non-equilibrium self-assembly, progressing continuously with time and the increasing proportion of the poor solvent. However, for SC12 with enhanced hydrop
