To enable the progression of organic electronic devices and applications into mainstream consumer products, fundamental material performance parameters need to reliably exceed current state of the art. This presentation outlines the chemical design approaches in the development of semiconducting small molecules and polymers for use in a range of functional electronic applications such as transistors for displays and biological sensing. The focus will on the understanding and control of microstructure and energy levels in conjugated aromatic semiconductors and their subsequent impact on device properties. Molecular design strategies to enable high performance devices will be demonstrated, with case studies illustrating contributions in a range of application areas. These include optimising charge transport in organic field effect transistors, where non-covalent intramolecular interactions were demonstrated to minimise energetic disorder in thin films, as well as electrical sensing of biologically relevant cations and metabolites.
