Abstract

The Metal-Organic Framework (MOF) field has seen a meteoric rise in popularity since the year 2000, to the point where MOFs or related materials now account for nearly 10% of all entries in the Cambridge Structural Database. However, despite years of focused worldwide research efforts, MOF-based technologies continue to be hampered by recurring issues around stability and cost, which limit their potential application scope. One route to improving the prospects of these materials is in wider exploration of ligand-centred functionality. Surprisingly, despite the vast number of MOFs which have been reported (which cover most of the naturally-occurring metals in the periodic table) the vast majority are constructed from just a small handful of ligand classes: aromatic carboxylates, imidazolates/benzimidazolates, and symmetric pyridines, pyrazolates or phosphonates.


Our goal is to explore a wider range of nitrogen heterocycles as ligands in MOFs, to take advantage of the excellent resistance to hydrolysis offered by strong metal-azolate bonds, and the additional opportunities for hydrogen bond stabilisation or further backbone functionality in these systems.

Our focus has been on three particular classes of heterocyclic linkers:
· Indazoles and pyrazolopyridines
· Pyrazole-fused cycloalkanes
· Pyrrolo[3,2-b]pyrroles


Each class shows useful properties when acting as ligands in extended networks,3 and this seminar will outline our progress in developing stable, functional MOFs from these building blocks.
