In biological systems, morphological transformations of nano/microstructures in response to environmental stimuli are integral to many of the processes necessary for life. Synthetic nanostructures that can similarly undergo morphological transitions in response to physical and chemical stimuli have attracted a great deal of attention, particularly for the development of smart functional materials. Herein, we developed a facile method for synthesizing polymer nanocapsules and thin films by multiple in-plane stitching of monomers through the formation of reversible disulfide linkages. Owing to the reversibility of the disulfide linkages, the nanostructured materials readily transform their structures in response to environmental changes at room temperature. For example, in reducing environments, the polymer nanocapsules release loaded cargo molecules. Moreover, reversible morphological transformations between these structures can be achieved by simple solvent exchanges. This work is a novel approach for the formation of robust nano/microstructured materials that dynamically respond to environmental stimuli.
