Functionalized Zr-UiO-67 metal-organic frameworks: Structural landscape and application

UiO based metal-organic frameworks (MOFs) have attracted much attention of many scientists among the large family of Zirconium MOFs. UiO-series including UiO-66, -67 and -68 which possesses high stability, tunability, porosity, and functions, are rapidly extending field in metal-organic frameworks since 2008. This progress in this family of MOFs, extended to the ability of linkers to be functionalized and led to generate new crystalline materials with desired properties and applications. This review presents comprehensively all of the reported functionalized and unfunctionalized UiO-67 MOFs in terms of structural classification. The overall framework of UiO-based MOF constructed from three different linkers including 4,4'-biphenyl dicarboxylic acid (bpdc), 2,2'-bipyridine-5,5'-dicarboxylic acid (bipydc) and 2-p henylpyridine-5,4'-dicarboxylic acid (ppydc). Also, the metalation of these linkers within MOFs investigated. Furthermore, a brief study on the application of the UiO-67-based MOFs was conducted. (C) 2021 Elsevier B.V. All rights reserved.
