Abstract

Self-assembly of short peptides stands as a pivotal avenue in the development of functional materials. Herein we report a flexible transformation during humidity-induced actuation of triglycine crystals with a sheet conformation, which originates from the strengthening of water hydrogen bonding to form hydrated triglycine crystals exhibiting a polyproline II conformation.
