Metal–Organic Framework (MOF) Defects under Control: Insights into the Missing Linker Sites and Their Implication in the Reactivity of Zirconium-Based

Abstract

<p> <span>The formation of the UiO-67 family of Zr MOFs is explored here through the prism of their acid-modulated growth, showing it to be key factor in controlling the MOF defect content, porosity, particle size, and morphology. The dynamic nature of the resulting Zr_{<font size="2">6</font>}-monocarboxylate (&rdquo;missing linker&rdquo;) defect sites is explored for UiO functionalization (through acid exchange), &ldquo;healing&rdquo; and the introduction of a catalytically active M(III) cation.</span></p>
