Supramolecular assemblies are constructed from at least two molecules through various noncovalent bonding modes such as hydrogen bonding, cationic–anionic electrostatic interactions, aromatic interactions, metal–ligand bonding, hydrophobic–hydrophilic interactions, and charge-transfer interactions. Owing to the dynamic and reversible nature of these noncovalent bonds, the assembly and disassembly of these molecules are dynamic and reversible. Molecules self-assemble to form the most conformationally and thermally stable structures through these noncovalent interactions. The formation of these noncovalent interactions is affected by the properties of the environment such as its polarity, temperature, and pressure; thus, the structure of the assembled compounds is determined by the environment. The sizes and shapes of the supramolecular assemblies play an important role in determining their functions. Therefore, controlling their size and shape is important. Introducing stimuli-responsive groups into supramolecular assemblies is a useful way to control their size and shape. Controlling supramolecular structures and motions with external stimuli, i.e., periodic and rotational motions on the molecular scale, structures, and molecular weights at the nano- and micrometer scales, visible shrinking/expansion, and adhesive behavior at a macroscopic scale, is very useful.

响应响应的超分子组装由柱[ n ]芳烃。

超分子组装体由至少两个分子通过各种非共价键模式构成，例如氢键，阳离子-阴离子静电相互作用，芳族相互作用，金属-配体键，疏水-亲水相互作用和电荷转移相互作用。由于这些非共价键的动态和可逆性质，这些分子的组装和拆卸是动态和可逆的。分子通过这些非共价相互作用自组装形成最构象和热稳定的结构。这些非共价相互作用的形成受环境性质（例如其极性，温度和压力）的影响。因此，组装化合物的结构取决于环境。超分子组装体的尺寸和形状在确定其功能中起着重要作用。因此，控制它们的尺寸和形状很重要。将刺激反应性基团引入超分子组装体是控制其大小和形状的有用方法。用外部刺激控制超分子的结构和运动，即在纳米和微米尺度上的分子尺度的周期性和旋转运动，结构和分子量，在宏观尺度上的可见的收缩/膨胀和粘合行为，是非常有用的。
