Inspired by protein polymerizations, much progress has been made in making "polymer-like" supramolecular structures from small synthetic subunits through non-covalent bonds. A few regulation mechanisms have also been explored in synthetic platforms to create supramolecular polymers and materials with dynamic properties. Herein, a type of reactive regulator that facilitates the dimerization of the monomer precursors through dynamic bonds to trigger the supramolecular assembly from small molecules in an aqueous solution is described. The supramolecular structures are crystalline in nature and the reaction coupled assembly strategy can be extended to a supramolecular assembly of aromatic amide derivatives formed in-situ. The method may be instructive for the development of supramolecular nanocrystalline materials with desired physical properties.
受蛋白质聚合反应的启发，通过非共价键由小型合成亚基制备“类聚合物”超分子结构已取得了很大进展。在合成平台中也探索了一些调控机制，以制备具有动态性质的超分子聚合物和材料。在此，描述了一种反应性调节剂，其通过动态键促进单体前体的二聚化，从而触发水溶液中小分子的超分子组装。超分子结构本质上是晶体，并且反应耦合组装策略可扩展到原位形成的芳族酰胺衍生物的超分子组装。该方法对于开发具有所需物理性质的超分子纳米晶体材料可能具有指导意义。
