Tunable Interactions of Polyoxometalate-Based Brushlike Hybrids in Solvents of Variable Quality: From Self-Recognition to Supramolecular Recognition
The controllable interactions of a spherical polymer brush modeled by a poly(styrene-b-4-vinylpyridinium methyl iodide)-polyoxometalate composite micelle, SVP-6, with a polyoxometalate-based supramolecular star polymer, PSP-4, in solvents of variable quality allow us to tune their self-assembly behaviors from self-recognition to supramolecular recognition. In the former case, isolated, contracti...

Nonionic Cyclodextrin Based Binary System with Upper and Lower Critical Solution Temperature Transitions via Supramolecular Inclusion Interaction
A nonionic binary aqueous interaction system consisting ofβ-cyclodextrin trimer (β-CD
3) and naphthaleneterminated poly(ethylene glycol) (PEG-NP2), which has tunable upper critical solution temperature (UCST) behavior around room temperature and lower critical solution temperature (LCST) behavior at high temperature, was investigated. In the UCST transition, gel-like aggregat...

[ChemCommun]Self-healable macro-/microscopic shape memory hydrogels based on supramolecular interaction
A simple strategyis provided to construct novel supramolecular hydrogels with both self-healing and shape memory properties.Starting from achieving self-healable hydrogel based on dynamicinteraction ofphenylboronic acid modified sodium alginate (Alg-PBA) and poly (vinyl alcohol) (PVA), further complex of alginate with Ca2+ render this hydrogel with the capability of shape memory inmacro-/microscop...

In situ electroactive and antioxidant supramolecular hydrogel based on cyclodextrin/copolymer inclusion for tissue engineering repair
The injectable electroactive and antioxidant hydrogels are prepared from mixing the tetraaniline functional copolymers and α-cyclodextrin (α-CD) aqueous solution. UV-vis and CV of the copolymer solution showed good electroactive properties. The antioxidant ability of the copolymer is also proved. The gelation mechanism and properties of the system are studied by WAXD, DSC, and rheometer. The enc...

A Supramolecular Janus Hyperbranched Polymer and Its Photoresponsive Self-Assembly of Vesicles with Narrow Size Distribution
Herein, we report a novel Janus particle and supramolecular block copolymer consisting of two chemically distinct hyperbranched polymers, which is coined as Janus hyperbranched polymer. It is constructed by the noncovalent coupling between a hydrophobic hyperbranched poly(3-ethyl-3-oxetanemethanol) with an apex of an azobenzene (AZO)
group and a hydrophilic hyperbranched polygl...

Investigation of supramolecular synthons of p-hydroxybenzoic acid (PHBA): Comparison of its hydrate, co-crystal and salt
An investigation of supramolecular synthons of p-hydroxybenzoic acid (PHBA) has been carried out in this work. Three different kinds of compounds derived fromPHBA (hydrate (1), co-crystal (2) and salt (3)) have been synthesized and characterized by single-crystal X-ray diffraction, infrared spectroscopy, differential scanning calorimetry (DSC) and thermogravimetric analyses (TGA). A thorough struc...

108.Enhanced thermal stability of organogels through self-reinforcing supramolecular assembly of a cholesterol–polyoxomatalate–cholesterol hybrid gelator
We report our study on the enhanced thermal stability of organogels through forming self-reinforcing supramolecular assemblies of a polyoxometalate (POM)-containing hybrid gelator. The designed and synthesized gelator has a molecular structure of cholesterol–POM–cholesterol. In our experiment, we found an intriguing phenomenon: the hybrid gelator could dissolve in toluene at 80 C and the soluti...

[Chem Commun] A Microcontacting Printing Induced Supramolecular Self-Assembled Photo Active Surface for Patterning Polymer Brushes
A facile and robust strategy for creating micropatterned polymer brushes via the combination of micro-contact printing (μCP) induced supramolecular self-assembled photo active surface with subsequent self-initiated photografting and photopolymerization (SIPGP) is reported. The results contribute to polymeric functionalization on a wide range of hydroxylated surface or graphene based materials

Interfacial organization-induced supramolecular chirality of the Langmuir-Schaefer films of a series of PPV derivatives
This paper reports the supramolecular chirality from optically inactive polymers through
an interfacial organization at the air/water interface. A series of poly(phenylenevinylene) (PPV) derivatives with dimethyloctyloxyphenyl substitutents were designed, and their spreading Langmuir monolayers as well as Langmuir-Schaefer (LS) films were investigated. The films were characterized b...

103.POM–Organic–POSS Cocluster: Creating A Dumbbell-Shaped Hybrid Molecule for Programming Hierarchical Supramolecular Nanostructures
We report the construction of dumbbell-shaped hybrid molecules for programming their hierarchical supramolecular nanostructures through a synergetic self-assembly. Our first dumbbell-shaped hybrid molecule is a POM−organic−POSS
cocluster produced by covalently coupling a POM cluster and a POSS cluster together through an organic tether. Structural analyses demonstrated a highly ordere...
