A copper based metal-organic framework: Synthesis, modification and VOCs adsorption
2018
Abstract A new copper (II) metal-organic framework Cu-MOF based on the ligand of 5-aminoisophthalic acid (AIPA) has been synthesized. Single-crystal X-ray structural analysis confirmed the formation of this compound, namely [Cu(AIPA)·DMF] n . The crystal structure exhibits a 2D sheet, which generate a 3D framework through non-classical hydrogen bond interactions. TGA, IR and VT-PXRD have been carried out to characterize the compound's thermal stability and purity. The as-synthesized sample was activated by removal of the coordination DMF solvent to afford porous framework Cu-MOF (1) without degradation of the original crystallinity. As the model of volatile organic compounds (VOCs), formaldehyde capture studies have shown that Cu-MOF (1) exhibits a versatile behavior for toxic gas accumulation.
