Abstract

Metal-organic frameworks (MOFs) are an expansive class of extended solids formed by coordination bonding between metal ions/clusters and organic ligands. Although MOFs are best known for their intrinsic porosity, they are now also emerging as an unusual set of porous, electrical, and ionic conductors that could address a number of applications in energy storage and generation. In this review, we focus on intrinsic ionic conductivity in MOFs and outline approaches for achieving high ionic conductivities. First, we highlight the use of noncoordinating acidic groups to integrate anions into MOF organic linkers. Next, we discuss the use of open metal sites to anchor anions and generate mobile ions. Then, we discuss the use of postsynthetic modifications to graft anions onto ligands and defect sites. Finally, we outline several unexplored approaches to improving ionic conductivity in MOFs and highlight several potential new applications. Expected final online publication date for the Annual Review of Materials Research, Volume 52 is July 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

教金属-有机框架传导:金属-有机框架中的离子和电子传递

金属有机骨架(mof)是一类由金属离子/簇与有机配体之间的配位键形成的扩展固体。尽管mof以其固有的多孔性而闻名，但它们现在也作为一种不寻常的多孔、电和离子导体出现，可以解决能源存储和发电方面的许多应用。在这篇综述中，我们重点讨论了mof的本征离子电导率，并概述了实现高离子电导率的方法。首先，我们强调使用非配位酸性基团将阴离子整合到MOF有机连接剂中。接下来，我们讨论了使用开放的金属位点来锚定阴离子并产生可移动离子。然后，我们讨论了利用合成后修饰将阴离子接枝到配体和缺陷位点上。最后，我们概述了几种尚未开发的提高mof中离子电导率的方法，并强调了几种潜在的新应用。预计《材料研究年度评论》第52卷的最终在线出版日期为2022年7月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。
