Spatiotemporal segregation of chiral supramolecular polymers

Programmable spatiotemporal control over the formation of func-tional supramolecular polymers, which leads to the formation of different morphological forms in solution, is one of the long-stand-ing issues in chemistry. The situation is even more complex espe-cially when dealing with a mixture of species in multicomponent self-assemblies. One way to achieve this goal is by controlling the spatiotemporal distribution of the molecular components in solu-tion, which control the overall aggregation process. Herein, we report the spatiotemporal segregation of different redox-respon-sive supramolecular assemblies inside spatiotemporal domains generated within the same solution under out-of-equilibrium conditions by using audible sound. Using this approach, we can spatiotemporally control the formation of at least two types of assemblies, which are either both achiral or one of them is chiral, or both are chiral but with opposite helicity. This strategy may pro-vide advanced control over solution-state synthesis of supramolec-ular polymers, which exhibit morphology-dependent functions.

Programmable control over the formation of functional supramolecular polymers, which leads to different morphological forms in solution, is a long-standing issue in chemistry. In this study, we report the spatiotemporal segregation of redox-responsive supramolecular assemblies inside spatiotemporal domains generated within the same solution under out-of-equilibrium conditions by using audible sound. This strategy allows for the spatiotemporal control of the formation of at least two types of assemblies with different chiralities and morphologies.
