Many useful principles of self-assembly have been elucidated through studies of systems where multiple components combine to create a single structure. More complex systems, where multiple product structures self-assemble in parallel from a shared set of precursors, are also of great interest, as biological systems exhibit this behavior. The greater complexity of such systems leads to an increased
通过对多个组件组合形成单一结构的系统的研究,已经阐明了许多有用的自组装原理。更复杂的系统,其中多个产品结构从一组共享的前体并行自组装,也引起了人们的极大兴趣,因为
生物系统表现出这种行为。然而,此类系统的复杂性越高,导致不形成离散物种的可能性就越大。在这里,我们展示了自组装动力学如何控制由五种结构单元的混合物形成的多种
金属有机结构,从而防止形成中等尺寸的离散结构。通过改变
配体对称性、齿数和方向,我们探索了五种不同的多面体(四面体、八面体、立方体、立方八面体和三棱柱)如何围绕 CoII 模板离子协同组装。解释了将组件组织成特定形状的基本规则,解释了原则上可以形成五个离散实体时仅形成三个离散实体的原因。
