Synthesis of novel porous coordination polymers, their characterization and solvothermal stability
Ondrušová, Soňa ; Lang, Kamil (advisor) ; Tyrpekl, Václav (referee)
This diploma thesis builds on the already published work, in which phosphinate analogs of terephthalic acid were used to prepare new stable metal-organic frameworks (MOFs) Fe-ICR- 2 and Fe-ICR-4. With the use of analogous biphenylene linkers, two new Fe-MOFs were prepared - Fe-ICR-6 and Fe-ICR-7. Isoreticular MOFs were also prepared using Al3+ metal centers. These materials were characterized by X-ray powder diffraction and adsorption isotherm measurements. Their solvothermal stability was measured after shaking and refluxing in water, ethanol, and toluene and activation from water. Furthermore, their thermal stability and the disintegration mechanism in air were determined by thermal analysis. Keywords: coordination polymer, metal-organic framework, stability, phosphinate
