Biographical Sketch

Prof. Ward obtained a BA in Chemistry from the University of Cambridge in 1986. This was followed by a PhD from the same institution in 1989, after which he became a postdoctoral research associate at the Université Louis Pasteur de Strasbourg. In 1990 he was appointed as Lecturer at the University of Bristol, where he was subsequently promoted to Reader and Professor. In 2003 he was appointed as professor of Inorganic Chemistry at the University of Sheffield. He was Head of Department of Chemistry from 2007 to 2011 and again from 2015 onwards.

Research Interests

MDW fig 1My research interests cover all aspects of the preparation, structural characterisation, and physical properties (electrochemical, magnetic, optical and photophysical) of complexes based on transition-metal (d-block) and lanthanide (f-block) elements. As such the work is interdisciplinary and covers many aspects of inorganic, organic, physical and materials chemistry. Currently active areas of interest include the following.

Self-assembly and host-guest chemistry of supramolecular cage complexes.

Reaction of relatively simple bridging ligands with labile first-row transition metal ions can afford remarkably elaborate high-nuclearity cage complexes which bind anionic guests in their central cavity. In some cases the central anions act as templates to induce the assembly of the cage around them. The largest example we have characterised so far is a tetra-capped, truncated tetrahedral cage containing sixteen Zn(II) ions, twenty four bridging ligands, and thirty two anion. Such cage complexes are of interest not only for their structures but also for their host-guest chemistry associated with anion uptake into their central cavities, and their photophysical properties.

Photophysical properties of polynuclear assemblies.

MDW fig 2 Complexes in which a light-absorbing group with a long excited-state lifetime (commonly, a Ru(II)-polypyridyl unit) is attached to a metal fragment which can use the excited-state energy, either in a redox reaction or by accepting it to enter an excited state of its own, are of particular interest in a variety of fields ranging from solar energy harvesting, luminescent cellular probes, and display devices.  Particular emphases at the moment are on:

(i) the use of transition metal compleses as chromophores to sensitise luminescence from lanthanides in mixed d/f complexes; this can lead to two-component (blue and red) luminescence which combines to give white light from a single molecule (see Figure);

(ii) use of luminescent cyanometallate complexes such as [Ru(bipy)(CN)4]2- as components of supramolecular assemblies via participation of the cyanide units in coordination to other metal ions, or hydrogen- or halogen- bonding;

(iii) Use of picosecond time-resolved infra-red spectroscopy to understand photoinduced energy and electron transfer in polynuclear assemblies.
