Reduced Symmetry Metal–Organic Cage‐to‐Framework Materials

open access: yesAngewandte Chemie, EarlyView.
A series of Ag(I) MOFs was synthesised from organic cages of varying structure and symmetry as linkers. Minor variations in the cage linkers were shown to significantly influence the structures of the resulting MOFs. This work represents the first incorporation of reduced symmetry (including chiral), intrinsically porous building blocks into MOFs, and ...

Metal‐Free Active Template: A Straightforward Route to 4‐Aminopyridinium‐Based Rotaxane Molecular Shuttles

open access: yesAngewandte Chemie, EarlyView.
Leigh's metal‐free active template‐based SNAr of an amine on halogenopyridiniums, in the presence of a crown ether, successfully afforded 4‐aminopyridinium‐containing rotaxanes. Further molecular machinery was carried out by deprotonation‐then‐carbamoylation of the conjugated amino moiety.

Cyclo‐Polyproline: Chameleonic All‐Peptide Macrocycles With Induced‐Fit Host‐Guest Recognition

open access: yesAngewandte Chemie, EarlyView.
Macrocycles served as the genesis of supramolecular chemistry, advancing synthetic, separation, and materials fields. Despite their utility, they typically lack synthetic control. This work establishes a robust platform for all‐peptide macrocycles capable of host‐guest complexation and chameleonic behavior.
