Research in The Forgan Group

The Forgan group is broadly interested in self-assembly, with current focus on metal-organic frameworks (MOFs). MOFs are self-assembled constructs wherein metal or metal cluster 'joints' link organic 'struts' to form highly interconnected hollow networks which often display permanent porosity. The ability to trap and store small molecules within MOFs leads to a number of potential applications.

We are grateful for funding from the ERC, EPSRC, Royal Society, STFC and the University of Glasgow.

Enhanced Reactivity and Properties in Porous Materials

Metal-organic frameworks contain arrays of ordered nanoscale pores which are often accessible to outside reagents by diffusion throughout the nanoporous network. Confining reagents within these 'molecular flasks' can dramatically alter their reactivity and regioselectivity, and facilitate their molecular sensing. The Forgan Group are exploiting this enhanced reactivity phenomenon to generate heterogeneous biomimetic catalysts - artificial enzymes - through extensive pore functionalisation and templated-directed synthesis. These studies (EPSRC grant EP/L004461/1) are underpinned by the Forgan Group's continuous investigations into the fundamentals of molecular recognition within MOFs themselves.

Drug Delivery from Functionalised Porous NanoMOFs

MOFs are being increasingly utilised to store and deliver molecular cargos to treat disease. The Forgan Group has developed a simple but effective methodology to produce bespoke, highly functionalised MOF nanoparticles to be used as targeted drug delivery vectors. In concert with our continuing interest in the interactions between MOF scaffolds and substrates, we aim to produce theranostic nanomaterials targeted at imaging and remedying specific ailments (ERC Starting Grant 677289).

Crystallisation and Mechanical Properties of High Valent MOFs

The Forgan group has conceived novel synthetic methodologies to enhance the crystallinity and control physical properties of high valent MOFs, allowing access to single crystals of otherwise unavailable MOFs. These breakthroughs have facilitated comprehensive studies of the MOFs under high pressure, elucidating mechanical properties, and led to the development of new postsynthetic modification protocols with applications in permanent sequestration of toxic gases.
