Reported here are the new concept of utilizing open metal sites (OMSs) for architectural pore design and its practical implementation. Specifically, it is shown here that OMSs can be used to run extended hooks (isonicotinates in this work) from the framework walls to the channel centers to effect the capture of single metal ions or clusters, with the concurrent partitioning of the large channel spaces into multiple domains, alteration of the host-guest charge relationship and associated guest-exchange properties, and transfer of OMSs from the walls to the channel centers. The concept of the extended hook, demonstrated here in the multicomponent dual-metal and dual-ligand system, should be generally applicable to a range of framework types.
这里报道的是一种利用开放金属位点（OMSs）进行孔结构设计的新概念，以及其实践应用。具体而言，本文表明，OMSs 可用于将延长的钩子（在这项工作中为异烟酸酯）从骨架壁延伸至通道中心，以捕获单个金属离子或簇，同时将大通道空间分割成多个区域，改变主客体的电荷关系和相关客体交换性质，并将 OMSs 从骨架壁转移至通道中心。本文在多组分双金属和双配体体系中展示了这种延长钩子的概念，它应该适用于一系列骨架类型。
