Synthesis of stimuli-responsive nanosized ring-like colloids and cyclic polymers via a dual-template approach

Abstract

A dual-template approach was developed for the first time to prepare stimuli-responsive nanosized ring-like colloids and cyclic polymers.

Stimuli-Responsive Supramolecular Chirality Switching and Nanoassembly Constructed by n-Shaped Amphiphilic Molecules in Aqueous Solution

“…Supramolecular nanoarchitectures prepared from low-molecular-weight organic blocks via reversible and directional noncovalent interactions (dynamic nature) have been extensively applied in fields ranging from optical and electronic to medical and environmental chemistry systems. − Small π-conjugated units with structural diversity comprising distinctive shapes and sizes have been used to develop regular supramolecular structures with high practicality. − Among the various molecular self-assemblies, rod–coil systems with functional groups are emerging as attractive multifunctional materials that have been employed to generate stimuli-responsive assemblies through self-arrangement and phase-separation of dissimilar molecular components under chemical or physical stimuli. − Functional groups are sensitive to specific forms of external stimuli, such as CO 2 , enzymes, pH, and light. Among these stimuli, light and heat are considered the most common and do not lead to the generation of chemical waste in self-assembled systems.…”

Controlled Synthesis of Cyclic‐Helical Polymers with Circularly Polarized Luminescence

“…For example, cyclic polymers have smaller hydrodynamic volume, lower melt viscosity, higher glass‐transition temperatures, and distinct self‐assembly behavior. In addition, various applications of the polymers have been revealed, such as drug delivery, rheological modifiers, plasticizers, lubricants, polymer building block, supramolecular, and material chemistry [4–11] . The new biological importance of viral cyclic deoxyribonucleic acid (DNA) and plasmids emphasizes and stimulates enthusiasm in the area of cyclic polymers [4] .…”

[4][5][6][7][8][9][10][11] The new biological importance of viral cyclic deoxyribonucleic acid (DNA) and plasmids emphasizes and stimulates enthusiasm in the area of cyclic polymers. [4] Although efforts have been made to overcome the constraints in synthesizing cyclic polymers, available strategies for the efficient and scalable synthesis of cyclic polymers are limited.…”
