Supramolecular Copolymers Driven by Quadruple Hydrogen Bonding and Host-Guest Interactions

A supramolecular array of fullerenes by quadruple hydrogen bonding.

Supramolecular Copolymer Constructed by Hierarchical Self- Assembly of Orthogonal Host−Guest, H‐Bonding, and Coordination Interactions

Supramolecular copolymers with complex architectures and emergent functions constitute a class of challenging but enticing synthetic targets in polymer science. Individual building blocks can be tailored to endow a resulting supramolecular copolymer with increased structural and functional complexity. Herein, we describe the construction of a linear supramolecular copolymer comprising mechanica...

Host-guest complexation driven dynamic supramolecular self-assembly.

Host-guest complexation between pillararene trimer 1 and biviologen 2 was used to fabricate the dynamic supramolecular self-assembly, which exhibits a reversible multidimensional transformation from 0D to 3D upon concentration changes. As a comparison, assemblies built by the complexation between 1,4-dimethoxypillar[5]arene and 2 only show spherical morphology under similar conditions.

Hybrid host-guest complexes: directing the supramolecular structure through secondary host-guest interactions.

A set of four hybrid host-guest complexes based on the inorganic crown ether analogue [H12W36O120]12- ({W36}) have been isolated and characterised. The cluster anion features a central rigid binding site made up of six terminal oxygen ligands and this motif allows the selective binding of a range of alkali and alkali-earth-metal cations. Here, the binding site was utilised to functionalise the ...

Olefin metathesis and quadruple hydrogen bonding: a powerful combination in multistep supramolecular synthesis.

We show that combining concepts generally used in covalent organic synthesis such as retrosynthetic analysis and the use of protecting groups, and applying them to the self-assembly of polymeric building blocks in multiple steps, results in a powerful strategy for the self-assembly of dynamic materials with a high level of architectural control. We present a highly efficient synthesis of bifunc...
