Dynamic Adaptive Two-Dimensional Supramolecular Assemblies for On-Demand Filtration

Summary: The construction of synthetic two-dimensional (2D) materials designates a pathway to the versatile chemical functionality by spatial control. However, current 2D materials with intelligence of stimuli-responsibility and adaptiveness have been unfledged. The approach reported here uses a sup...
