(674c) Controlling the Ion-Doping Mechanism in Defective UiO-66

Defect engineering the highly stable metal-organic framework, UiO-66, has been a popular research topic over the past several years. Since the surge in research on this subject, little attention has been given to the implications for the ion-doping mechanism and, ultimately, potential methods for functionalizing UiO-66. We propose post-synthetic procedures for two distinct ion-doping mechanisms: one involving the incorporation of exchange ions into the framework, and another involving the generation of “extra-framework” surface cations. The UiO-66 sample was doped with cations and characterized using various techniques. The adsorption of polar gases is shown to be enhanced with the introduction of surface cations into the framework, demonstrating a mechanism that can be exploited for selective adsorption applications.
