Experimental Studies of Synthesis and Adsorption on two Lanthanide Based MOFs

Metal-organic frameworks are porous materials resulting from the coordination of a metal ion (the Lewis acid) and organic polydentated ligands. In the case of the MOFs, the SBU (Secondary Building Unit) is defined by taking the active groups of the ligands involved in coordination and the metal ion as a block. The remaining part of the organic ligand is therefore called simply a linker, so that MOFs can also be defined, in a supra-molecular view, as a material composed of SBUs and linkers combined together to form regular, periodic and porous structures. The possible textures and the possible combinations are virtually infinite, depending especially on the properties ofthe linkers, much more than of the metal ions involved, in order to design the pore size, the pore dimensionality and the catalytic properties. It gives this class of nano-materials a very interesting perspective in the most various applications, by allowing to ”tune” each relevant chemical or physical parameter concerning porous materials and their applications in nanotechnology
