Research

Polymerisation catalysis

With the plastics industry set to continue its worldwide growth, future increased competitiveness will no doubt lead to the demand for improved processing of known polymers and the desire to make new innovative polymers. To this end we are interested in design of coordination and/or organometallic precatalysts for the controlled synthesis of polymeric products including polyolefins and biodegradable polyesters. To enhance the catalyst performance, a variety of multidentate ligand architectures are screened that can be readily modified in terms of both their steric and electronic properties.

Ring opening polymerisation of epsilon-caprolactone

To support our programme a range of specialised screening facilities, including a parallel screening reactor for rapid catalyst evaluation and a single-cell high pressure system for more in-depth studies are accessible.

Organobimetallic transformations

The presence of two distinct metal centres fixed in close proximity offers considerable opportunities for the study of the relative reactivities of the two different metal sites, while cooperative interactions between the two different metal centres may lead to complexes exhibiting unique types of reactivity.

X-ray structure of a mixed-metal Ni···Pd complex

We are looking at the reactivity patterns exhibited by M2 or MM' bimetallic species supported on the same ligand framework, whereby the metal centres are enforced into either remote or closely located positions, with a view to exploring their catalytic applications (e.g., small molecule or polymerisation/oligomerisation).

    New inorganic materials

    Strategies for the development of molecular and hydrogen-bonded assemblies for applications in catalysis and magnetism represents an on-going research area. As part of collaboration with the Space Research Centre (SRC) in Leicester we are also developing inorganic materials for applications in X-ray polarimetry. Such transition metal-based systems present a simple filter technology that could add polarimetry capability to future large effective area X-ray astronomical observatories.

    Highly ordered copper(II) halides that display X-ray dichroism at copper K-edge

    Through a combination of theoretical studies and inorganic synthesis, single crystals are being evaluated for their dichroic response using various synchrotron facilities.

    Additional Information - methodology and techniques

    All of this work provides excellent opportunities for developing skills in inorganic and organic synthetic techniques, including the use of Schlenk-line and glove-box techniques. The characterisation of the new compounds, their reactivity and physical studies will be carried out using a combination of state of the art equipment.
