Stimuli-Triggered Dynamic Transformations in Supramolecular Polymers

“…The noncovalent connection renders inherent responsiveness to supramolecular polymers . For example, the strength of hydrogen bonds varies with solvent and temperature, making them suitable for constructing stimuli-responsive supramolecular polymers that react to changes in solvent polarity and heat. − Particularly, temperature increases can significantly reduce viscosity, facilitating the processing of supramolecular polymeric materials and enabling applications in inkjet printing or coatings for thermosensitive substrates. , In addition to the inherent responsiveness, another intriguing strategy is to incorporate additional stimuli-responsive units into supramolecular polymers. This allows for tailored responses to specific stimuli such as pH values, , chemical additives, , light, − redox, , or mechanical force. − Stimuli-responsiveness can modify the intrinsic properties of monomeric building blocks or influence their noncovalent bonding mode.…”

“…Several comprehensive reviews have highlighted stimuli-responsive supramolecular polymers, categorized by either the different types of noncovalent driving forces or the varied external stimuli. , Additionally, certain reviews have discussed stimuli-triggered property changes triggered by specific light stimulus. ,, Herein, we focus on summarizing the different types of dynamic transformations within the supramolecular polymer field, which have yet to be summarized in previous reviews. Specifically, stimuli-responsive dynamic transformations in supramolecular polymers are classified into the following five categories (Figure ): (i) stimuli-triggered depolymerization of existing supramolecular polymers into monomers (Section ); (ii) stimuli-triggered transformations within different types of supramolecular polymers (Section ); (iii) stimuli-induced poststabilization of supramolecular polymers as a special case of Section (Section ); (iv) stimuli-triggered activation of a “dormant” monomer toward in situ supramolecular polymerization (Section ); (v) stimuli-induced transient supramolecular polymerization with programmable lifetimes (Section ).…”
