Synthesis and Characterisation of Metal-Organic Frameworks

Abstract

The first chapter of this thesis includes a brief introduction to metal organic frameworks (MOFs) and the aims of this thesis.

The use of two dipyridyl-type linkers depicted in Figure 1 in combination with various benzene dicarboxylate linkers for the synthesis of mixed-linker MOFs is investigated in chapter 2.

In chapter 3 six new compounds containing caldc ligand (25,26,27,28- tetrapropoxycalix[4]arene-5,17-dicarboxylate) were synthesised and characterised. Adsorption of methane, hydrogen, and their equimolar mixtures were studied by molecular simulations by our collaborators from University of Edinburgh.

In chapter 4 a new molybdenum diphosphonate network structure has been prepared and structurally characterised. It shows reversible dehydration, which occurs with a structural change. The dehydrated material is able to adsorb methanol but not ethanol.

The synthesis, structures, and magnetic properties of three new anionic copper(II) sulfate aggregates and chains linked into 2-D and 3-D networks involving the dimethylammonium cations (NMe2H2+) are reported in chapter 5.
