Cucurbit[8]uril-based supramolecular polymers: promoting supramolecular polymerization by metal-coordination.
نویسندگان
چکیده
Linear supramolecular polymers were obtained in aqueous solution by employing cucurbit[8]uril-based host-guest interaction as the driving force. Water-soluble monomers were prepared through direct metal-coordination. The rigid and bulky terpyridine-Fe linker can effectively enhance the monomer's solubility and suppress its cyclization, thereby promoting supramolecular polymerization.

The construction of rigid supramolecular polymers in water through the self-assembly of rod-like monomers and cucurbit[8]uril.
Two new types of supramolecular polymers have been constructed via the self-assembly of rigid rod-like monomers and cucurbit[8]uril (CB[8]) in water. These supramolecular polymers possessed rigid backbones and further aggregated into stick-like bunched fibres.
متن کاملAqueous interfacial gels assembled from small molecule supramolecular polymers
The self-assembly of a stimuli-responsive aqueous supramolecular hyperbranched polymer from small molecules is reported. This system is composed of ditopic and tritopic guest-functionalised molecules that are able to form heteroternary supramolecular complexes with the macrocyclic host cucurbit[8]uril (CB[8]). We demonstrate that the supramolecular hyperbranched polymer formed is responsive to ...
متن کاملToward a versatile toolbox for cucurbit[n]uril‐based supramolecular hydrogel networks through in situ polymerization
The success of exploiting cucurbit[n]uril (CB[n])-based molecular recognition in self-assembled systems has sparked a tremendous interest in polymer and materials chemistry. In this study, polymerization in the presence of host-guest complexes is applied as a modular synthetic approach toward a diverse set of CB[8]-based supramolecular hydrogels with desirable properties, such as mechanical str...
متن کاملCucurbit[8]uril directed stimuli-responsive supramolecular polymer brushes for dynamic surface engineering.
In situ modification of surfaces with thin layers of polymers is of growing interest as adjustment of surface properties can be made on demand. We present herein a supramolecular 'grafting to' polymer brush via the recognition of surface-bound cucurbit[8]uril (CB[8]) rotaxanes towards end-functionalised polyethylene glycol (PEG). This dynamic supramolecular method represents advantages over tra...
متن کاملDual-responsive supramolecular colloidal microcapsules from cucurbit[8]uril molecular recognition in microfluidic droplets†
The macrocyclic host, cucurbit[8]uril, is used to facilitate cross-linking of colloidal particles and polymers in microdroplets resulting in thermoand photo-responsive supramolecular colloidal microcapsules. Methyl viologen-bearing colloidal particles were prepared using template polymerisation and combined with cucurbit[8]uril and an azobenzene-functionalised polymer within microfluidic drople...
