Three dimensional (3D) supramolecules with giant cavities are attractive due to their wide range of applications. Herein, we used pentatopic terpyridine ligands with three types of coordination moieties to assemble two giant supramolecular hexagonal prisms with a molecular weight up to 42 608 and 43 569 Da, respectively. Within the prisms, two double-rimmed Kandinsky Circles serve as the base surfaces as well as the templates for assisting the self-sorting during the self-assembly. Additionally, hierarchical self-assembly of these supramolecular prisms into tubular-like nanostructures was fully studied by scanning tunneling microscopy (STM) and small-angle X-ray scattering (SAXS). Finally, these supramolecular prisms show good antimicrobial activities against Gram-positive pathogen methicillin-resistant Staphylococcus aureus (MRSA) and Bacillus subtilis (B. subtilis).

We report a new design of polymer-patched gold nanoparticles (AuNPs) with controllable interparticle interactions in terms of their direction and strength. Patchy AuNPs (pAuNPs) are prepared through hydrophobicity-driven surface dewetting...
In this study,w ee stablished af easible strategy to construct an ew type of metallo-polymer with helicoidal structure through the combination of covalent polymerization and intramolecular coordination-driven self-assembly.I nt he design, at etratopic monomer (M)w as prepared with two terminal alkynes in the outer rim for polymerization, and two terpyridines (TPYs) in the inner rim for subsequent folding by selective intramolecular coordination. Then, the linear covalent polymer (P)w as synthesized by polymerization of M via Glaser-Hay homocoupling reaction. Finally,i ntramolecular coordination interactions between TPYs and Zn(II) folded the backbone of P into aright-or left-handed metallo-helicoid (H) with double rims.O wing to multiple positive charges on the inner rim of helicoid, double-stranded DNAm olecules (dsDNA) could interact with H through electrostatic interactions.R emarkably,d sDNAa llowed exclusive formation of H with right handedness by means of chiral induction.
