I completed my PhD in Chemistry at the University of Canterbury, New Zealand in 2012 under the supervision of Prof Paul Kruger, where I studied the coordination chemistry of pyrazole and indazole ligands in helicates and coordination polymers. Afterwards, I spent 3 years as a postdoctoral researcher at Monash University, Australia working on Metal-Organic Frameworks for carbon dioxide capture in the groups of Prof Stuart Batten and Dr David Turner, on a collaborative project funded by the Science and Industry Endowment Fund (SIEF).

In 2015 I relocated to Trinity College Dublin, Ireland to take up an Irish Research Council Postdoctoral Fellowship, working with the group of Prof Thorri Gunnlaugsson on fluorescent coordination polymers for chemical sensing. Following this I was appointed as a Lecturer in Inorganic Chemistry in the School of Chemical and Physical Sciences at Keele University in late 2017.

My research interests are based in supramolecular coordination chemistry and the synthesis of functional and responsive materials. In general, my research projects involve a substantial component of single-crystal X-ray crystallography, using laboratory and synchrotron sources, to probe the fascinating structural chemistry of these systems. As well as a large synthetic chemistry component, my research involves a wide variety of physical and spectroscopic characterisation techniques, and research projects can readily be tailored to the particular interests of students.

My current research is focused in two broad categories:

1) Metal-Organic Frameworks for adsorption, extraction and separation

Chris Hawes Research 1

Metal-Organic Frameworks (MOFs) are an exciting class of coordination compounds in which metal ions are linked by bridging ligands into crystalline, polymeric networks. These materials contain nanoscale pores which can be chemically tailored for carrying out specific functions. As well as their excellent potential for CO2 capture, my interest in these materials is their ability to selectively extract and concentrate dissolved species from the solution phase, which has particular relevance for chemical separation and extraction technologies. I am especially interested in developing new ligand systems for these materials, to incorporate additional chemical functionality or unusual structural properties.

2) Fluorescent sensing in coordination polymers and polynuclear coordination compounds

Chris Hawes Bio Pic 2

Fluorescent sensors are an attractive prospect for a broad range of applications, including environmental monitoring, quality assurance and security, because of the excellent sensitivity which can be achieved in these systems. My goal is to use the principles of host-guest chemistry and a class of particularly environment-sensitive fluorophores to develop fluorescent sensors for weakly-interacting analytes which do not undergo strong analyte-fluorophore interactions. These sensors are constructed within metallo-supramolecular systems, including cages, MOFs and metallogels, giving wide scope for utility. Mixtures containing organic analytes which are incapable of quenching fluorescence (thereby being difficult to detect) are particularly interesting targets for this study.
