    Synthesis of multicomponent metal-organic frameworks and investigations of their physical properties : a thesis presented in partial fulfilment of the requirements of the degree of Doctor of Philosophy in Chemistry at Massey University, Manawatu, New Zealand

    Multicomponent metal-organic frameworks (MOFs) are built up from multiple ligands that are geometrically distinct. These ligands occupy specific positions in the MOF lattice. Installing different functionalities at precise locations in the framework is an important step in making MOFs for specific applications. This can be achieved by designing functionalized ligands for multicomponent MOFs. This study was, firstly, focused on design and synthesis of new linkers. The study then covered preparation of a number of quaternary MOFs. Furthermore, the study was focused on the physical and chemical properties of these MOFs, such as their catalytic activity, gas adsorption and fluorescence behaviours.

    Metal-organic frameworks for selective gas separation : a thesis presented in partial fulfilment of the requirements of the degree of Doctor of Philosophy in Chemistry at Massey University, Manawatū, New Zealand

    With an ever increasing need for a more energy-efficient and environmentally benign procedure for gas separation, adsorbents with tailored structures and tunable surface properties are in high demand. Metal–organic frameworks (MOFs), constructed from metalcontaining nodes connected by organic bridges, are such a new type of porous materials. They are promising candidates as adsorbents for gas separations due to their large surface areas, adjustable pore sizes and controllable properties, as well as acceptable thermal stability. However, the bottleneck in this context is that MOFs are expensive to be fabricated and majority of them are not stable in harsh environments, which are often required by industrial processes. In this thesis, we introduce three families of metal-organic frameworks with exceptional gas separation performance for a variety of different gas mixtures separation. Their unique separation performances are well supported by isotherm measurement, X-ray crystallography, DFT calculations, and breakthrough test. These MOFs are all readily synthesizable by inexpensive precursor and highly stable at extreme conditions.
