Abstract:
Metal organic frameworks MOFs are constructed from metal ions or metal ion clusters and bridging organic linkers, which provide diverse structural topologies with porous architectures. They have potential to be applied to molecular sieving, storage, ion exchange, heterogeneous catalysis, sensor technology, and optoelectronics. The robust open framework of the MOF can accommodate various guest molecules. The nanoporous lattices of MOFs have a high degree of chemical versatility and an immensely rich host guest chemistry that include reversible guest and ion exchange and heterogeneous catalysis. In this work, we have successfully introduced two small guest molecules, viz. 3-methoxypropionitrile and nitrobenzene, in a cage of host MOF Zn2NDC2DPNI-DMF. The complete exchange of the reagent solvent for the new guests has been verified by gas chromatography-mass spectrometry GC-MS, powder x-ray diffraction PXRD, thermogravimentric analysis TGA, and Fourier transform infrared FTIR.
