摘要：Controlling dynamic molecular self-assembly to finely tune macroscopic properties offers chemical solutions to rational material design.Here we report that combining disulfide-mediated ring-opening polymerization withβ-sheet-like H-bonding self-assembly can drive a direct small-molecular assembly into a layered ionic network with precise architectural tunability and controllable functions as ion-transport membranes.This strategy enables a one-step evaporationinduced self-assembly from discrete small molecules to layered ionic networks with high crystallinity.The interlayer distances can be readily engineered with nanometer accuracy by varying the length of the oligopeptide side chain.The synergy of the layered structure and hydrophilic terminal groups facilitates the formation and ordering of interlayer water channels,endowing the resulting membranes with high efficiency in transporting ions.Moreover,the inherent dynamic nature of poly(disulfide)s allows chemical recycling to monomers under mild conditions.We foresee that the robust strategy of combining dynamic disulfide chemistry and noncovalent assembly can afford many opportunities in designing smart materials with unique functions and applications.
