Post-Synthetic Annealing: Linker Self-Exchange in UiO-66 and its Effect on Polymer-MOF Interaction
Abstract
Post-Synthetic Exchange (PSE) and Defect Engineering have emerged as powerful techniques for tuning the properties and introducing novel functionality to Metal Organic Frameworks (MOFs). Growing evidence suggests that each technique plays a key role in the mechanism of the other: linker coordination chemistry is pivotal to defective frameworks, while defect sites can help initiate PSE. Here, the intersection of these approaches is explored by exchanging a MOF with linkers already present within the framework. Post-Synthetic Annealing (PSA) modifies a MOF’s properties by redistributing the framework’s mixture of bound linker/modulator species. Using changes to the polymer-additive interactions in PTMSP (poly-1-trimethylsilyl-1-propyne) nanocomposites observed through aging, we demonstrate that PSA causes one linker species to preferentially accumulate on the MOF’s crystal surface. Reaction conditions are shown to affect molecular composition of the resulting annealed UiO-66 MOFs; a finding explained through established reaction constants. This work simultaneously reveals intricacies of Post-Synthetic Modification (PSM) chemistry and presents a facile means of tuning MOFs and MOF nanocomposites.
