摘　　要：Synthetic molecules that form functional noncovalent assemblies in water have received much attention for their potential applications as biomaterials.In this work,we introduce a novel water-compatible monomer based on the phthalhydrazide moiety that assembles into hydrogen-bonded trimeric discs.In bulk,the material exhibits a cylindrical nanostructure in the liquid-crystalline phase at elevated temperatures,morphologically distinct from the crystalline lamellar phase.In water,these molecules effectively form cylinders in a one-dimensional fashion,yielding fibrous structures.The formation of these supramolecular polymers follows a cooperative mechanism,as evidenced by denaturation studies.The trimerized pattern represents a new category of aqueous su pramolecular polymers with future prospects for functional complex molecular systems.
