Mike Ward

Head of Department and Professor of Inorganic Chemistry


Mike WARD

Mike did his BA at Cambridge, studying Natural Sciences (1983-1986). He remained in Cambridge for his PhD (1986-1989) with Ed Constable, studying early examples of helicate complexes. After a post-doc with Jean-Pierre Sauvage in Strasbourg playing with catenates, he started his independent academic career in Bristol in 1990. After 13 years there he moved to Sheffield in 2003, and after 14 years in Sheffield, he moved to the University of Warwick in 2017 where he is currently Head of Department.

Mike's interests are all based around the coordination chemistry of transition metal and lanthanide ions and their multinuclear assemblies; in particular, current emphases in his research are (i) self-assembly and host-guest chemistry of hollow metal/ligand cage complexes, and (ii) photophysical properties of polynuclear complexes and supramolecular assemblies, including applications in imaging and sensing. Awards from the RSC for his research include the Corday Morgan medal for 1999, the 'Chemistry of the Transition Metals' award for 2005, and Supramolecular Chemistry award for 2016.

Mike has been involved with the RSC in various capacities including two stints on Dalton Council, one on the editorial board of Dalton Transactions, and was Editor-in-Chief of the journal ‘RSC Advances’ from 2011-17.

I am working on the following projects at the moment:

I am currently interested in two main areas of research, both based around coordination and supramolecular chemistry:

1) Self-assembly and host-guest chemistry of coordination cages.

Coordination cages are hollow, pseudo-spherical metal complexes which self-assemble from metal ions and bridging ligands. They have elaborate and beautiful structures, and can bind small molecule ‘guests’ in the central cavity. This host-guest chemistry can result in useful properties and applications such as catalysed reactions of guests bound in the cavity; pH-dependent uptake and release of drug molecules; binding of gas molecules; and photoinduced electron transfer from a cage to a bound guest.

2) Photophysical properties of metal complexes and metal complex assemblies.

Luminescence from metal complexes based on transition-metal (d-block) or lanthanide (f-block) ions has applications in a wide range of areas from solar energy harvesting to analysis and bio-imaging. We are interested in the fundamental studies and applications of luminescent metal complexes with a recent focus on analysis of chemical warfare agent simulants and imaging of cells.

Mike teaches the following undergraduate modules (2019/20):

CH267 (10 lectures on stability and reactivity of metal complexes; 10 lectures on organometallic chemistry)

CH222 (3 lectures introduction to mass spectrometry)
