Multicomponent self-assembly in one pot provides an efficient way for constructing complex architectures using multiple types of building blocks with different levels of interactions orthogonally. The preparation of multiple types of building blocks typically includes tedious synthesis. Here, we developed a multicomponent synthesis/self-assembly strategy, which combined covalent interaction (C-N bond, formed through condensation of pyrylium salt with primary amine) and metal-ligand interaction (N → Zn bond, formed through 2,2':6',2″-terpyridine-Zn coordination) in one pot. The high compatibility of this pair of interactions smoothly and efficiently converted three and four types of components into the desired complex structures, which are supramolecular Kandinsky Circles and spiderwebs, respectively.
一锅多组分自组装为使用具有不同层次相互作用的多种类型构建块以正交方式构建复杂结构提供了一种有效方法。多种类型构建块的制备通常包括繁琐的合成。在这里,我们开发了一种多组分合成/自组装策略,该策略将共价相互作用(通过吡喃鎓盐与伯胺缩合形成的 C-N 键)和金属-配体相互作用(通过 2,2':6',2″-三联吡啶-Zn 配位形成的 N → Zn 键)结合在一锅法中。这对相互作用的高兼容性平稳有效地将三种和四种类型的组分转化为所需的复杂结构,分别是超分子 Kandinsky Circles 和蜘蛛网。
