Supramolecular polymers constructed by orthogonal self-assembly based on host–guest and metal–ligand interactions
Peifa Wei,Xuzhou Yan,Feihe Huang +2 more
TL;DR: This critical review of the recent development of supramolecular polymeric systems involving metal-ligand interactions and host-guest molecular recognition is addressed and classified depending on the types of macrocyclic hosts are highlighted.

TL;DR: This work uses colloidal nanocrystals functionalized with light-responsive ligands that readily self-assemble and trap various molecules from the surrounding bulk solution and Illumination with visible light disassembles these nanoflasks, releasing the product in solution and thereby establishes a catalytic cycle.

para-Bridged symmetrical pillar[5]arenes: their Lewis acid catalyzed synthesis and host-guest property.
TL;DR: Condensation of 1,4-dimethoxybenzene with paraformaldehyde in the presence of BF3.O(C2H5)2 gave novel para-bridged pentacyclic pillar DMB (DMpillar[5]arene), which formed 1:1 host-guest complexes with dialkyl viologen and alkyl pyridinium derivatives.
Journal ArticleDOI
From supramolecular chemistry towards constitutional dynamic chemistry and adaptive chemistry
TL;DR: Supramolecular chemistry considers chemical objects and systems capable of responding to external solicitations by modification of their constitution through component exchange or reorganisation, and opens the way towards an adaptive and evolutive chemistry, a further step towards the chemistry of complex matter.

TL;DR: It is found that pronounced changes in colour and fluorescence emerge with the accumulation of plastic deformation, indicating that in these polymeric materials the transduction of mechanical force into the ring-opening reaction is an activated process.

Using the dynamic bond to access macroscopically responsive structurally dynamic polymers
TL;DR: The emergence of a new trend in the design of adaptive materials that involves the use of reversible chemistry to programme a response that originates at the most fundamental (molecular) level is described.
