高度稳定的二维单层组件（SLA）的合成是超分子科学中的一个关键挑战，特别是那些具有长程分子有序和明确形态的组件。在这里，通过双配体共组装策略合成了具有高热稳定性、溶剂稳定性和机械稳定性的薄（厚度<2 nm）三角形AuI-硫醇盐SLA。此外，由于长程各向异性分子堆积，SLA 显示出对外部刺激的装配级弹性和各向异性变形响应，这为 SLA 在仿生纳米力学中提供了新的应用潜力。
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 AuI‐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.
