  Metal organic frameworks(MOFs) arehybridthree-dimensional crystalline materials built frominorganicmetal ions or metal clusters connected with multidentateorganic linkers. MOFs are interesting materials because of itshigh surface area and easily tunable chemistry. The extensive toolkit developed for synthetic organic chemistrycan be utilized to simply changethe organic linkersboth before the assembly of the MOF but also on the crystalline solid. MOFs are excellent materials forapplication inmolecule adsorption and separation, electrochemistry, drug delivery and catalysis. One challenge withmetalorganic frameworksis their low thermal, chemical and mechanical stability. A relatively new group of MOFs discovered at University of Oslo(UiO)in 2008,is receiving enormous attentiondue to its superior thermal, chemical and mechanical stabilitycompared to other types of MOFs.The major experimental work in this thesis has been the synthesis of zirconium 2,6-naphthalene dicarboxylic(2,6-NDC)MOF, one of the least studied members of the UiO-Zr-MOF family.Missing linker and missing cluster defects have been observed and characterized for the zirconium 2,6-NDC MOF. The stability of the 2,6-NDC MOF in high humidity have been compared to UiO-66and UiO-67. The major characterization tools have beenpowder X–ray diffraction, thermogravimetric analysis, nitrogen adsorption, nuclear magnetic resonance and scanning electron microscope.
