Metal-Organic Frameworks (MOFs) are hybrid materials and are acknowledged as an important class of functional solid-state materials with high scientific interest in academia and industry alike. Their modular nature in terms of structural and compositional diversity, tunability, high surface area, and controlled pore size renders MOFs as the ideal candidate to address various persistent challenges pertaining to gas storage/separation, catalysis, drug delivery, and smart sensing. Through the field of reticular chemistry, targeted structures can be constructed through multiple design approaches, based on preselected building blocks prior to the assembly process.
This thesis illustrates the merit of the supermolecular building layer (SBL) approach for the rational construction and discovery of highly connected and porous MOFs based on rare earth cations. Specifically, the emphasis of this study is on (i) the rational design and synthesis of 3-periodic MOFs based on SBLs pillared by ditopic ligands through post-synthetic modification (PSM) and in situ reactions. (ii) The investigation of the mixed-ligand system with different lengths and geometry of ditopic ligands on the isolation of metal clusters with distinct pore sizes. (iii) Gaining an overall insight into the exploration of different synthetic pathways that control the assembly of rare earth MOFs.
