Organic molecules have become increasingly important in the last few decades in the development of high-tech electronics. These include organic light-emitting diodes (OLEDs) for flat screen display technology such as TVs. computers and mobile devices. Organics are also used as key components in light-harvesting devices for solar cells and as organic field effect transistors (OFETs) for microelectronics. Our research focuses on the fundamental interplay between molecular aynthesis, solid state structure and physical properties with a particular interest in magnetic, conducting and optical properties of the molecules we prepare.
Our approach is centered around the synthesis and reactivity patterns of group 15/16 heterocycles, particularly those containing the elements N,P, S and Se and the generation of stable free radicals. We exploit crystal engineering approaches to understand and design molecule based materials and use a range of in-house techniques for compound characterization including:
* NMR and EPR spectroscopies,
* UV/vis and fluorescence measurements,
* Single crystal and powder X-ray diffraction,
* DSC and TGA
* Computational studies (DFT).
Measurements of magnetic and conducting properties are undertaken through collaborations with internationally leading experts in the field.
