Research | Current

My research is broadly focused on the understanding and use of intermolecular interactions to achieve more sustainable chemical processes. Central to this is an understanding of solvents and solvent effects, particularly within new classes of solvents such as ionic liquids and deep eutectic solvents. By understanding these effects we aim to develop new solvents that can perform existing processes more effectively by influencing reaction rates, solution equilibria or solubility; or design entirely new processes. Projects span a range of traditional areas within chemical science and feature collaborations with other research groups both within the School of Chemical Sciences as well as with national and international collaborators.

Examples of some areas of interest are highlighted below:

Controlling Reactivity using Structured Solvents

Ionic liquids and deep eutectic solvents that contain amphiphilic ions are capable of forming nanostructures that possess well-defined polar and non-polar regions. These nanostructures offer the possibility of controlling chemical reactivity not only through direct solvent-solute interactions but also by affecting how solutes partition within the solvent. We are interested in understanding the formation of these nanostructures and their influence on chemical reactivity towards designing and developing new solvents capable of facilitating complex multistep reactions in a more efficient manner which generates less chemical waste.

Solvents for More Selective Separations and Extractions

We are interested in the development of new, non-hazardous solvents to accomplish the selective extraction and separation of high value compounds from renewable sources or for use in the processing of pharmaceuticals. Solvent design is informed by our understanding of solvent effects and the use of empirical and theoretical methods of classifying solvent properties. 

New Approaches to Metal-Free Hydrogenation

The ability to perform catalytic hydrogenation chemistry without the use of transition metals has rapidly developed over the past decade. We have discovered that solvent selection can have a significant impact on the performance of these catalysts and are exploring the synergistic combination of solvent and catalyst selection to increase the scope of metal-free hydrogenation chemistry with the aim of reducing the use of toxic, scarce and environmentally hazardous transition metal catalysts.

Solvent Effects on Intermolecular Forces

It has been recently appreciated that halogens, pnictogens and chalcogens can participate in so-called sigma-hole interactions where the halogen, pnictogen or chalcogen interacts with an electron rich acceptor atom, akin to the more well-known hydrogen bond. One of the remarkable features of these interactions is that they are generally unaffected by solvent polarity, unlike hydrogen bonding interactions. We are interested in exploring the generality of this effect in unconventional media and the development of these interactions in the design of new functional materials.
