【Chem. Eur. J】Lyotropic Supramolecular Helical Columnar Phases Formed by C-3-Symmetric and Unsymmetric Rigid Molecules
Unlike thermotropic liquidcrystalline C-3-symmetric molecules with flexible chains, the herein-designed fully rigid three-armed molecules (C-3-symmetric and unsymmetric) create a fancy architecture for the formation of lyotropic liquid crystals in water. First, hollow columns with triple-stranded helices, analogous to helical rosette nanotubes, are spontaneously constructed by self-organization of...

【European Polymer Journal 】Multiscale fibers via supramolecular self-assembly of a fully rigid, discotic aromatic aramid molecule
We synthesized a fully rigid, water soluble discotic-shaped aromatic aramid molecule, which can spontaneously self-assemble into multiscale fibers (from nano- to micro-scale in both length and diameter), depending on the molecular states (e.g., solution, liquid crystals and solid state). In diluted solution (below 0.086 g/mL), the discotic molecule tend to self-assemble into nanofibers. As the con...

A Supramolecular Gel Based on An Adenine Symmetrically Grafted Anderson-Type Polyoxometalate Complex.
An Anderson-type polyoxometalate was covalently decorated by using adenine on both sides. Through cation substitution, we obtained a new hybrid building block with long alkyl chains for supramolecular gels. According to the synergetic effect of hydrogen bonding of inter adenine units and van der Waals interaction of side alkyl chains, the DODA3[A-MnMo6-A] gelator can stabilize solvent a...

Borinic acid block copolymers: new building blocks for supramolecular assembly and sensory applications
Borinic acid block copolymers have been prepared by reversible addition-fragmentation chain transfer (RAFT) polymerization and investigated as “smart materials” in sensory applications. Taking advantage of the hydrogen bond donating ability of the borinic acid groups, supramolecular aggregates of PNIPAM-b-PBA were generated by complexation with P4VP. The P4VP complex showed greatly improved fluo...

Non-covalent Interaction Cooperatively Induced Stretchy, Tough and Stimuli-Responsive Polyurethane-Urea Supramolecular (PUUS) Hydrogels
Up to now, fabrication of strong and stimuli-responsive supramolecular hydrogels via an easy molecular design and synthesis procedure is still a big challenge. In this work, a series of hydrophobically modified linear polyurethane–urea copolymers and one polyurethane copolymer were prepared via a greatly simplified one-pot approach to investigate the synergistic effect between hydr...

Mechanically strong and stretchable polyurethane–urea supramolecular hydrogel using water as an additional in situ chain extender
Mechanically strong hydrogels have attracted much interest as a result of their potential applications as biomaterials. However, it is still a challenge to produce mechanically strong supramolecular hydrogels because of the inherently weak characteristics of non-covalent interactions. A novel polyurethane–urea supramolecular hydrogel with excellent mechanical properties was develop...

Mechanically strong and stretchable PEG-based supramolecular hydrogel with water-responsive shape-memory property
A strong and highly stretchable supramolecular hydrogel with a shear modulus of 200 kPa, an elongation at break of 770% at 4 MPa stress and a water-responsive shape-memory property is developed. The whole shape-memory procedure including shape deformation, fixing
and recovery can be realized under mild and green conditions, i.e. in air and water.

Core-Shell Capsules Based on Supramolecular Hydrogels Show Shell-Related Erosion and Release Due to Confinement
Hydrogel-containing core–shell capsules are useful as drug delivery vehicles for many
biomedical applications, especially when release of incorporated guests can be controlled.
Here, we developed a one-step organic solvent-free method to prepare such core–shell
capsules using a synthetic and a natural supramolecular hydrogel, for the core and shell, respectively. A solution containing ...

[Chem. Commun] Reversible morphology transitions of supramolecular polymer self-assemblies for switch-controlled drug release
A novel method for switch-controlled drug release was developed through the reversible morphology transitions of supramolecular branched copolymer self-assemblies. The reversible transitions from vesicles to nanoparticles were successfully achieved by alternating UV and visible light irradiation to obtain morphology-controlled drug release in a switch mode.
In this st...
