Generation of Defect‐Modulated Metal–Organic Frameworks by Fragmented‐Linker Co‐Assembly of CPO‐27(M) Frameworks
EUROPEAN JOURNAL OF INORGANIC CHEMISTRY(2015)
摘要
The generation of defect-modulated metal-organic frameworks (MOFs) by the successful stepwise doping of 2-hydroxyterephthalate (BDC-OH) into frameworks of the CPO-27-M type is discussed. The influence of Mg-II, Co-II, and Ni-II ions on the product formation has been investigated by powder XRD (PXRD), IR spectroscopy, and thermal analysis. To establish the successful incorporation of the fragmented linker molecule, H-1 NMR spectra were recorded after the digestion of the MOFs in DCl/[D-6]dimethyl sulfoxide. After the incorporation of BDC-OH, microporous structures were generated with reasonable porosity. The morphologies of the reaction products were checked by SEM measurements, and no significant changes to the morphologies were observed after the fragmented-linker doping.
