Metal‐Organic Frameworks with Rod Yttrium Secondary Building Units

Abstract

AbstractWe report a new hydroxamate‐based yttrium MOF, named MOF‐419 [Y(HCOO)(BDH)], with rod‐SBUs. The compound was synthesized employing chelating construction of benzene‐1,4‐hydroxamate (BDH2−) linkers, and the use of formic acid as the modulator was found to be crucial for the formation of rod‐shaped SBUs. MOF‐419 shows permanent porosity and has a BET surface area of 1130 m2/g. Its hydrophobic pore environment and gas sorption properties were demonstrated through the combination of single crystal X‐ray diffraction and nitrogen, carbon dioxide, and water sorption experiments. We envision that these results will aid the study and understanding of rod MOFs with chelating linkages.
