This work presents an experimental investigation of water adsorption in metal−organic frameworks (MOFs) at room temperature and up to 90% relative humidity. Structural degradation of the materials after regeneration is analyzed via powder X-ray diffraction (PXRD) and nitrogen adsorption measurements. MOFs with open metal sites are quite hydrophilic but appear to maintain their structure according to PXRD. However, significant surface area loss indicates that decomposition is occurring and is likely an attribute of oxygen presence during the regeneration procedure. Materials with copper paddle-wheel (HKUST-1), 5-coordinated magnesium (Mg MOF-74), and 7-coordinated zirconium (UiO-66(-NH 2 )) maintain good structural stability, while Zn-COOH containing MOFs (DMOF-1; DMOF-1-NH 2 ; UMCM-1) undergo complete loss of crystallinity.

In this paper, we report on a high‐throughput (gram quantities) solvothermal method for the synthesis of copper terephthalate metal–organic frameworks in dmf. While the structure of MOF‐2 and some of the associated polymorphs are well known, we know of no equivalent structural studies for the isostructural copper terephthalate (Cu–tpa). The material we have made crystallizes in the C2/m space group. Cu–tpa also exhibits reversible solvent‐exchange properties. These properties make this material useful for potential applications in gas storage and catalysis applications. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

In the synthesis of the microporous metal-organic framework copper 1,4-benzenedicarboxylate [Cu(BDC)], solvent exchange with methanol prior to recrystallization lowers the desolvation temperature to 160°C and produces more crystalline Cu(BDC). The solution to the crystal structure of Cu(BDC) has been determined by using ab initio quantum molecular calculations and refinement with synchrotron Xray powder diffraction data. This solution is in the P1 space group with a = 5.25 Å, b = 9.67 Å, c = 10.77 Å, α = 90.29°, β = 91.06°, γ = 92.413°, and V = 546.04 Å 3 . The Brunauer-
