Description
Summary:[Display omitted] •An anionic MOF, UiO-67-NSO2CF3, was newly synthesized through post-synthetic modification of UiO-67-NH2 framework.•The UiO-67-NSO2CF3 showed high porosity even after the introduction of bulky functional group.•The framework structure was maintained during the post-synthetic process. We newly synthesized an anionic porous MOF, UiO-67-NSO2CF3 ((HPy)6[Zr6O4(OH)4(BPDC-NSO2CF3)6](guest)n (H2BPDC-NSO2CF3 = (4,4′-dicarboxy-[1,1′-biphenyl]-2-yl)((trifluoromethyl)sulfonyl)amide, HPy+ = pyridinium), having large pore size through post-synthetic method. The amino groups (–NH2) on the UiO-67-NH2 were converted into –NSO2CF3– groups. The sample was characterized with X-ray powder diffraction, scanning electron microscope observations, SEM combined with energy-dispersive X-ray spectroscopy, infrared spectra, thermogravimetry, and N2 adsorption isotherms measurements. These measurements revealed that the successful synthesis of the porous MOF, UiO-67-NSO2CF3.
