Abstract
Artificial supramolecular nanostructures showing transient properties have attracted significant attention in recent years. New discoveries in this area may provide insights into a better understanding of the sophisticated organization of complex biomolecular systems. Nevertheless, research concerning such materials is still limited. Better knowledge of the chemical reactivity and corresponding molecular transformations of self-assembling molecules, which guide their assembly/disassembly, may provide an opportunity to construct transient supramolecular nanostructures capable of showing chemical stimulus responsiveness. Herein, we report a short peptide derivative containing a hydrazone bond, which shows transient hydrogel formation (no only sol-to-gel but also gel-to-shrunken gel phase transition) accompanied by continuous transformation and growth of supramolecular nanostructures triggered by hydrazone-oxime exchange reaction in response to hydroxylamine. Such controlled shrinkage behavior of supramolecular hydrogels in response to specific chemical stimuli has rarely been explored compared with conventional polymer hydrogel systems.

Abstract
AbstractVarious biofunctional hydrogel materials can be fabricated in aqueous media through the self-assembly of peptide derivatives, forming supramolecular nanostructures and their three-dimensional networks. In this study, we describe the self-assembly of new Fmoc-dipeptides comprising α-methyl-L-phenylalanine. We found that the position and number of methyl groups introduced onto the α carbons of the Fmoc-dipeptides by α-methyl-L-phenylalanine have a marked influence on the morphology of the supramolecular nanostructure as well as the hydrogel (network) formation ability.
