Organometallic Chemistry

Organometallic research at Dublin City University is currently focused on the photochemical and kinetic properties of organometallic compounds. Our research is primarily based on a study of the reactivity of co-ordinatively unsaturated species and more recently on photinduced insertion processes. The reactive species formed photochemically are characterised from a mixture of kinetic and thermodynamic data utilising UV-vis. laser flash photolysis and matrix isolation techniques.

One particular area that we have become involved in recently, is the photochemistry of heteroaromatic metal carbonyl compounds of d 6 or d 7 metals. These systems tend to be extremely photolabile and exhibit a wavelength dependent photochemistry. For instance a photoinduced insertion into a C-Se bond has been observed recently.

More recently research within the group has extended to the development of theoretical models to describe organometallic compounds, at present we are using ab initio techniques (Gaussian 03). The ultimate aim of these calculations is to predict the photochemistry of the organometallic system and to understand the properties and behaviour of reactive fragments.
