Recent developments in kinetically controlled supramolecular polymerization permit control of the size (i.e., length and area) of self-assembled nanostructures. However, control of molecular self-assembly at a level comparable with organic synthetic chemistry and the achievement of structural complexity at a hierarchy larger than the molecular level remain challenging. This study focuses on controlling the aspect ratio of supramolecular nanosheets. A systematic understanding of the relationship between the monomer structure and the self-assembly energy landscape has derived a new monomer capable of forming supramolecular nanosheets. With this monomer in hand, the aspect ratio of a supramolecular nanosheet is demonstrated that it can be controlled by modulating intermolecular interactions in two dimensions.
动力学控制的超分子聚合的最新进展使得能够控制自组装纳米结构的尺寸（即长度和面积）。然而，在与有机合成化学相当的水平上控制分子自组装以及在大于分子水平的层次上实现结构复杂性仍然具有挑战性。本研究聚焦于控制超分子纳米片的纵横比。对单体结构与自组装能量景观之间关系的系统理解催生了一种能够形成超分子纳米片的新型单体。有了这种单体，超分子纳米片的纵横比被证明可以通过在二维中调节分子间相互作用来控制。
