Nonlinear optical materials and Near Infrared dyes A series of "push-pull" stilbene derivatives have been prepared as part of a Training and Mobility of Researchers Network Project and this work is now being further developed with the objective of preparing materials with strong near infrared absorptions (see also here). Such materials have many potential applications such as in optical recording devices, as diagnostic reagents and in photodynamic therapy. We are also examining potential extensions of this work to dendrimeric materials.

Sterically demanding aromatic compounds A catalytic organometallic route leading to the efficient preparation of a number of sterically hindered aromatic hydrocarbons, phenols, anilines and heterocycles has been developed (see here) and these products are now being investigated further as starting materials for the synthesis of Schiff base ligands for metal complexes and of lipophilic bio-active compounds (see above)
High energy techniques
Ultrasound and microwaves are becoming increasingly important tools for the organic chemist. The group has recently initiated the use of these techniques and this expertise will be reinforced by the input from incoming post-doctoral fellows and expert labs (Prof. D. Walton, Coventry; Prof. A. Loupy, Paris; Prof. M. Bradley, Edinburgh) as part of the Marie Curie Transfer of Knowledge project. "SOPHOLIDES" which has recently started.
