Helicates are a defining element of DNAs and proteins, with functions that critical to variety biological processes. Cyclodextrins promising candidates for forging multiple-stranded helicates well-defined helicity, but lack available tools has precluded the construction artificial helical nanochannels controllable geometry helicity from these widely chiral building blocks. Herein, we disclose family Ag6L2 can be readily assembled α-cyclodextrin-derived ligands through coordination between pyridinyl groups Ag+ cations. We discovered exhibit either an M or P when cations adopt tetrahedral while losing most their linearly coordinated. Both precisely controlled by simply changing number methyl at ortho positions ligands. The tetracoordinated interconnect into infinite two-dimensional coordinative network characterized hexagonal tessellation. Theoretical calculations, which reveal lower energies conformations observed in crystals compared those inverted counterparts, support experimental results.

The chirality of helical polypeptides is correlated to that their constituent amino acid residues. For with non-natural backbones, however, such correlations are less clear. Here, circular double helices torus knot/link topologies were assembled from metal-peptide chains composed Ag(I) ions and ditopic tripeptides Gly-Gly-Ala Gly-Ala-Gly sequences. We found the structures determined by l-Ala's dihedral angles. A tubular dimeric structure an M21L14 composition was further achieved via additional metal cross-linking, showing rational design potential for artificial peptide helices.

A 90-membered macrocycle having two functional moiety, diphenyl-phenanthroline (dpp) and tri-dentate pyridine-diamide (pda) as templating center has been synthesized from precursor molecules via amide bond formation in 10 steps. dpp pda are arranged alternatively around the a sequence of dpp-pda-dpp-pda demeostrated orthogonal behaviour, when treated with transition metal such Cu(I) Co(III): It forms figure eight complexes selectively between units respectively due to geomtric preferance. This makes operates bimodal manner. Interconversion witnessed by metal-exchange demetalation subsequent re-metalation centres. Removal template is performed using common less toxic reagent NH2CH2CH2NH2 Co(III) Zn/CH3COOH at RT.
