Highly Stable Triangular Single‐Layer 2D Assemblies: Synthesis and Their Stimuli‐Responsive Elastic and Anisotropic Curling

Abstract

Synthesis of highly stable two-dimensional single-layer assemblies (SLAs) is a key challenge in supramolecular science, especially those with long-range molecular order and well-defined morphology. Here, thin (thickness < 2 nm) triangular Au I -thiolate SLAs with high thermo-, solvato-and mechano-stability have been synthesized via a double-ligand co-assembly strategy. Furthermore, the SLAs show assembly-level elastic and anisotropic deformation responses to external stimuli as a result of the long-range anisotropic molecular packing, which provides SLAs with new application potentials in bio-mimic nanomechanics.
