[Chemical Science] Stretchable Supramolecular Hydrogels with Triple Shape Memory Effect
Shape memory polymers on the basis of reversible supramolecular
interactions have invoked growing research interest, but still suffer from
limitations such as poor mechanical strength and finite shape memory
performance. Here, we present a novel mechanical stretchable supramolecular
hydrogel with triple shape memory effect at macro/micro scale. The introduction
of double network concept into supra...

[Polym.Chem.]PGMA-based supramolecular hyperbranched polycations for gene delivery
Supramolecular chemistry has been widely applied in biomedical fields. It was reported that the topological structure has effects on the performance of gene delivery systems. Supramolecular polymer-like gene carriers with hyperbranched topological structures have still not been reported. In this work, a series of ethanolamine functionalized polyglycidyl methacrylate (PGMA)-armed AB2 ty...

【Macromol. Rapid Commun】Mechanical Robust and Self-Healable Supramolecular Hydrogel
Development of self-healing polymers with spontaneous self-healing capability and good mechanical performance is highly desired and remains a great challenge. Here, mechanical robust and self-healable supramolecular hydrogels have been fabricated by using poly(2-dimethylaminoethyl methacrylate) brushes modified silicananoparticles (SiO2@PDMAEMA) as multifunctional macrocrosslinker...

【Chem. Commun】Anisotropic ionic conductivities in lyotropic supramolecular liquid crystals
The designed aromatic amide discotic molecule with sulfonic acid groups at its periphery exhibits a hexagonal supramolecular columnar liquid crystalline phase, which leads to the achievement of anisotropic ionic conductivity through macroscopically aligning the ionic channels.

A processable hybrid supramolecular polymer formed by base pair modified polyoxometalate clusters.
A new type of organic–inorganic hybrid supramolecular polymer has been prepared by using the base group modified polyoxometalate clusters as monomers, where the hydrogen bonds between the complementary base pairs act as the driving force.

Integrative self-sorting: a versatile strategy for the construction of complex supramolecular architecture.
Large protein-sized synthetic supramolecular architecture is rare and certainly has not yet achieved the
structural and functional complexity of biomolecules. As multiple, identical copies of a few building
blocks are repetitively used, a highly symmetrical architecture results with limitations in function. In
marked contrast, functional structures in nature are often assembled with hig...

Supramolecular hydrogels co-loaded with camptothecin and doxorubicin for sustainedly synergistic tumor therapy
The co-delivery of multiple drugs has become the primary strategy in cancer therapy in recent years,
because this technique could promote synergistic actions, reduce side effects and deter the
development of drug resistance. To achieve a controlled and sustained release of the loaded drugs, a
supramolecular hydrogel based on the host–guest interactions between a hyperbranched polyglyce...

Ultraductile, Notch and Stab Resistant Supramolecular Hydrogels via Host-guest Interactions
Various supramolecular materials, especially hydrogels, based on host–guest interactions have been widely studied due to their attractive properties and potential applications. However, many of their practical uses are still severely limited by their poor mechanical performance. In this report, we present a novel kind of supramolecular hydrogel showing extremely ductile, notch and ...

Tough Stimuli-Responsive Supramolecular Hydrogels with Hydrogen-Bonding Network Junctions
Hydrogels were prepared with physical crosslinks
comprising 2-ureido-4[1H]-pyrimidinone (UPy) hydrogen-
bonding units within the backbone of segmented
amphiphilic macromolecules having hydrophilic poly(ethylene
glycol) (PEG). The bulk materials adopt nanoscopic physical
cross-links composed of UPy?UPy dimers embedded in segregated hydrophobic domains dispersed within the PEG matrix as co...

Multistimuli Responsive and Electroactive Supramolecular Gels Based on Ionic Liquid Gemini Guest
Electroactive supramolecular gels with multistimuli responsiveness were fabricated through host?guest interactions between a host polymer containing β-cyclodextrin (CD) and an
ionic liquid (IL) type asymmetric gemini guest, which contains both ferrocene (Fc) and bis(trifluoromethyl-sulfonyl)imide (TFSI?) as the respective α- and ω-guest groups. Owing to the multiple sti...
