受蛋白质聚合的启发，在通过非共价键从小合成亚基制造“类聚合物”超分子结构方面取得了很大进展。一些调节机制也在合成平台上进行了探索，以创建具有动态特性的超分子聚合物和材料。本文描述了一种通过动态键促进单体前体二聚化以触发水溶液中小分子超分子组装的反应性调节剂。超分子结构本质上是结晶的，反应耦合组装策略可以扩展到原位形成的芳酰胺衍生物的超分子组装。该方法对开发具有理想物理性能的超分子纳米晶材料具有指导意义。
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.
