动力学控制下的分子自组装有许多机会导致新的现象和应用。然而，仍然缺乏对复杂动力学行为的机械洞察。在这里，我们表明，即使是一个微妙的变化，分子结构的亚稳态超分子组装的动力学行为的影响。有趣的是，动力学过程以与热力学模型预测相反的方式影响最终结果（在本研究中，纳米片结构）的大小。我们的研究结果说明了分子自组装和动力学控制的分子自组装之间的差异。我们相信，这项研究将扩大分子自组装的潜在应用。
Molecular self-assembly under kinetic control has many opportunities leading to novel phenomena and applications. However, a mechanistic insight into the intricate kinetic behavior is still lacking. Herein, we demonstrate that even a subtle change in the molecular structure affects the kinetic behavior of metastable supramolecular assembles. Interestingly, the kinetic process influenced the size of the final outcomes (in this study, nanosheet structures) in a manner opposite to that predicted by the thermodynamic model. Our findings illustrate the difference between thermodynamically and kinetically controlled molecular self-assemblies. We believe that this study will expand the potential applications of molecular self-assemblies.
