Our research is centered around the chemistry of singlet oxygen (¹O₂), the lowest excited state of the dioxygen molecule. We have been exploring reactions of singlet oxygen with heteroatoms such as phosphorus and sulfur. We are especially interested in mechanistic pathways of such oxidation reactions. Kinetic measurements, trapping experiments and low-temperature observation of reactive intermediates are performed to understand what type of peroxidic intermediates are formed. It is important to understand the nature of such reactive intermediates because they are often better oxidants than dioxygen (in its triplet or singlet state) itself.

We are also interested in the development of non-porphyrin, metal based sensitizers and the use of nanopartcles and quantum-dot-porphyrin hybrids as efficient sensitizers. More about singlet oxygen can be read here.
