2. Synthetic studies of nitrogen containing heterocycles, particularly pyrazole and benzotriazine derivatives
Abstract : This thesis will mainly focus on the chemistry of nitrogen containing heterocyclic compounds, particularly pyrazole and benzotriazine and related ring systems to these compounds. The first part includes a short introduction to biologically important compounds as well as a description of reactivity and chemistry of benzo[c]pyrazole (indazole) and its derivatives. READ MORE

5. Synthesis and Characterisation of Conjugated Polymers with High Electron Affinity
Abstract : This thesis describes synthesis and characterisation of conjugated polymers with high electron affinities. Polymers of this type are desired, for example, for use in light-emitting devices or as electron accepting material in photodiodes/solar cells. READ MORE
