南京工业大学Bai Junfeng团队报道了双壁Zn36Zn104多元金属有机多面体框架及其等网状演化。相关研究成果发表在2021年10月19日出版的《美国化学会杂志》。

金属-有机多面体框架在气体储存和分离方面极具吸引力,因为带有窗口的大空隙可以作为客体分子的陷阱。引入多变量/多组分功能是提高特定目标性能的方法。有机连接体的高兼容性可以产生多变量MOF,但到目前为止,单一金属-有机框架中二级构建单元(SBU)的多样性仍然有限(大多数情况下不超过两个)。

该文中,研究人员报道了一种新的双壁Zn36@Zn104金属-有机多面体框架(HHU-8),具有五种不同拓扑结构的SBU及其向Zn36@Zn136对应物(HHU-8s)。这两个MOF都是首次使用如此多的拓扑不同的SBU以及拓扑不同的节点构建的MOF,其形成和演化为SBU的可控性提供了新的见解。

Abstract: Metal–organic polyhedral frameworks are attractive in gas storage and separation due to large voids with windows that can serve as traps for guest molecules. Introducing multivariant/multicomponent functionalities in them are ways of improving performances for certain targets. The high compatibility of organic linkers can generate multivariant MOFs, but by far, the diversity of secondary building units (SBUs) in a single metal–organic framework is still limited (no more than two in most cases). Here we report a new double-walled Zn36@Zn104 metal–organic polyhedral framework (HHU-8) with five types of topologically distinct SBUs and its isoreticular evolution to the Zn36@Zn136 counterpart (HHU-8s). Both MOFs are the first to be constructed with such high numbers of topologically distinct SBUs as well as topologically distinct nodes, and their formation and evolution provide new insight into SBU’s controllability.
