Overview
- Development of new ligand frameworks for application in coordination chemistry and homogeneous catalysis
- Stereogenic-at-metal metal complexes
- Heterobimetallic systems as potential platforms for metallaphotoredox catalysis and/or biomedical application
- Configurational and conformational coordination control with asymmetric multidentate ligands
Most of our work encompasses aspects of synthetic organic, inorganic and organometallic chemistry with an emphasis on preparing new ligands and exploring their coordination chemistry and deployment in homogeneous catalysis. Inherently chiral bimetallic complexes are of particular interest.

Research
Metallaphotoredox catalysis
Catalysis is a crucial mechanism for the creation of a more sustainable manufacturing future by enabling lower energy pathways to the formation of life-affirming chemicals and materials. Photo-catalysis is an efficient process that is driven by sunlight reducing the reliance on fossil fuels as energy vectors. We are interested in constructing bifunctional, single-molecule catalysts capable of breaking and creating chemical bonds through the application of light. The combination of a photo-active and redox-active site in these bimetallic systems is the key design element for effective catalysis.
Stereogenic-at-metal complexes
We are interested in the controlled formation of stereogenic-at-metal (SAM) complexes where the metal itself is a source of chirality. Such complexes have potential in asymmetric catalysis and bio-medical applications. Control at the metal centre is is usually achieved through the use of bi- or multi-dentate ligands with prescribed chiral elements that enable selective construction of SAM complexes. We are investigating several types of novel ligand systems for the generation of new SAM systems of both a mono- and bi-metallic nature. The bimetallic complexes are of particular interest as we seek to control the stereochemistry at two metal sites through judicious choice of a support ligand(s).
