Understanding the role of solvent in translating molecular anisotropy to supramolecular polymers is in the early stages. A solvent’s influence on the strength of different noncovalent interactions can explain anisotropic growth in some cases, but its effect on cooperative processes, particularly in mixed solvents, remains obscure. We report the self-assembly of a series of chiral perylene bisimides in water–cosolvent mixtures, and the results highlight the fascinating influence of solvent–solute interactions on supramolecular anisotropy, both chiral and morphological. The initial assembly is agnostic to solvent composition, resulting in weakly chiral, spherical nanostructures. In an extremely narrow solvent composition range, the nanospheres transform into long, prominently chiral supramolecular polymers. Further, chirality can be fully reversed by changing the good (achiral) cosolvent. We elucidate how solvent modulates specific noncovalent interactions and governs the kinetics and thermodynamics of key processes, such as spontaneous phase segregation, secondary nucleation, and cooperative growth. In the context of supramolecular polymerization, our results encourage one to steer the focus away from the physical attributes of a solvent (polarity, phase diagram, etc.) and toward the complexities of solvent–solute interactions.

Molecular self-assembly constitutes a useful tool to construct discrete and functional nanostructures with well-defined properties. Nevertheless, understanding supramolecular order both in solution an...

Precise control over out-of-equilibrium states is key to creating smart materials. Here, we report a synthetic supramolecular polymer system that forms distinct out-of-equilibrium structures of different dimensionalities depending on light intensity. Real-time high-speed AFM imaging revealed the underlying mechanisms, including light-driven facet-selective polymorphic transformation and Ostwald ripening. This study offers a general design principle for adaptive materials whose structures and functions are finely tuned by the amount of energy input.
