“…To demonstrate the applicability of the self‐sorting approach, we further extended this strategy to the self‐sorting system of aliphatic and aromatic motifs . For this purpose, a bifunctional monomer (Np‐C n ‐Np) bearing an alkyl chain (C n ; n = 4, 6, 8, 10) and two naphthalene moieties (Np) was designed and prepared as shown in Figure .…”

Supramolecular polymers have attracted plenty of interest in the scientific community; however, developing controllable methods of supramolecular polymerization remains a serious challenge. This article reviews some recent developments of methods for supramolecular polymerization from controllable fabrication to living polymerization. Three facile methods with general applicability for controllable fabrication of supramolecular polymers have been established recently: the first method is a self-sorting approach by manipulating ring-chain equilibrium based on noncovalent control over rigidity of monomers; the second is covalent polymerization from supramonomers formed by noncovalent interactions; and the third is supramolecular interfacial polymerization. More excitingly, living supramolecular polymerization has been achieved by two elegant strategies, including seeded supramolecular polymerization under pathway complexity control and chain-growth supramolecular polymerization by metastable monomers. It is anticipated that this review may provide some guidance for precise fabrication of supramolecular polymers, leading to the construction of supramolecular polymeric materials with controllable architectures and functions.

“…Isothermal titration calorimetry (ITC) was used to investigate the interaction differences between cationic and zwitterionic amphiphile with EuW 10 in the supramolecular self‐assembly . As shown in Figure a, upon the addition of cation amphiphile C 12 mimBr into EuW 10 aqueous solution, a clear enthalpy change was observed and the binding constant was 3.31×10 3 m −1 , indicating that significant electrostatic interaction was present between the [EuW 10 O 36 ] 9− anion and [C 12 mim] + cation.…”

Coassembly of a Polyoxometalate and a Zwitterionic Amphiphile into a Luminescent Hydrogel with Excellent Stimuli Responsiveness

The co-existence of electrostatic attraction and repulsion between zwitterionic amphiphile and anionic polyoxometalate (POM) promotes the formation of aqueous inorganic-organic coassemblies. Injectable, luminescent supramolecular hydrogels have been fabricated by using this novel and versatile technique. Hydrogels with different characteristics can be flexibly manipulated by adjusting the molar ratios of compounds. Interestingly, a linear relationship between the luminescence intensity and temperature accompanying the sol-gel transition was observed. In addition, the emission properties of the hydrogels were sensitive to external acid and base gasses. Such multi-stimuli responsive luminescent hydrogels provide an attractive pathway to construct intelligent optical soft materials, especially for biological sensors for which stimuli responsiveness is necessary.

Supramolecular Interfacial Polymerization: A Controllable Method of Fabricating Supramolecular Polymeric Materials

A new method of supramolecular polymerization at the water–oil interface is developed. As a demonstration, an oil‐soluble supramonomer containing two thiol end groups linked by two ureidopyrimidinone units and a water‐soluble monomer bearing two maleimide end groups are employed. Supramolecular interfacial polymerization can be implemented by a thiol–maleimide click reaction at the water–chloroform interface to obtain supramolecular polymeric films. The glass transition temperature of such supramolecular polymers can be well‐tuned by simply changing the polymerization time and temperature. It is highly anticipated that this work will provide a facile and general approach to realize control over supramolecular polymerization by transferring the preparation of supramolecular polymers from solutions to water–oil interfaces and construct supramolecular materials with well‐defined properties.
