The self-sorting behavior of circular helicates and molecular knots and links.

Ayme JF, Beves JE, Campbell CJ, Leigh DA - Angew. Chem. Int. Ed. Engl. (2014)

Bottom Line: We report on multicomponent self-sorting to form open circular helicates of different sizes from a primary monoamine, Fe(II) ions, and dialdehyde ligand strands that differ in length and structure by only two oxygen atoms.The corresponding closed circular helicates that are formed from a diamine--a molecular Solomon link and a pentafoil knot--also self-sort, but up to two of the Solomon-link-forming ligand strands can be accommodated within the pentafoil knot structure and are either incorporated or omitted depending on the stage that the components are mixed.

Perfect self-sorting of remarkably similar ligand strands in the formation of circular helicatesof different sizes. A 1:1 ratio of aldehydes 1 and 2 was treated with two equivalents ofFeCl2 and four equivalents of n-hexylamine (3) in[D6]DMSO at 60 °C for 18 h, followed by anion exchangewith aqueous KPF6, thereby generating a mixture of circular helicates 4 and 5.
