Objective We propose a basic research study of mechanisms and conditions required for efficient dissociation/formation of excitons into (from) free charges in organic multilayers and the relation to the morphological parameters of the materials. In the first instance we will concentrate on studying the mechanisms referred to above and the dependence on the electronic structure of monomers, oligomers and specific molecules like C60 and TCNQ. From these basic studies we hope to ma judicious choices of systems which can be tested for device applications. For this a basic research study of the influence the morphological parameters is of great importance since these are known to strongly influence the efficiency of processes New in this proposal are the use of modern molecular beam epitaxy techniques to grow very well defined organic (multi)layers as well as the specific behavior and morphology of block copolymers combined with an in situ study of their electronic structure electrical transport and optoelectronic properties. Knowledge obtained here will be coupled back to the synthesis of new oligomers, monomers and polymers with the hope of further optimizing properties and for a directed effort in the development of multiblock copolymers incorporating all of the required functions for a device. Also judiciously chosen systems will be further studied with regard to the morphology as mentioned above. The development of efficient photovoltaic and electroluminescent devices is one of our long-term targets. Training content (objective, benefit and expected impact) The candidate has an excellent knowledge of and training on the structure of solid state polymers and polymer morphologies. Her involvement in the proposed project will enlarge her knowledge and skills on the functional (photonic, electronic, photovoltaic) properties of polymers and their relation to the structure and morphologies. An optimisation of the structure / morphology of the polymers will allow her to demonstrate the fabrication of efficient electroluminescent and photovoltaic devices Links with industry / industrial relevance (22) This research is related to other projects in which we are closely collaborating with companies such as Oce, Van der Grintz and IBM.
