The molecular interactions in SWCNT/conducting polymer composites and their influence on the doped state of these components is the main focus of the present research proposal. For this purpose model structures like SWCNT of different diameters and conduction mechanism on the carbon side and aniline oligomers and polymers on the polymer side are used to understand the doping of each component in a composite and the influence of the doping on the type and extension of the interaction of the components. Experimentally the study is preferably done by electrochemical and in situ ESR-UV-Vis-NIR spectroelectrochemistry to get a detailed information of the charged states of the organic structures of aniline oligomers and polymers like cation radicals, dications, polarons, bipolarons and polaron pairs. Using the in situ ESR-UV-Vis- NIR spectroelectrochemical methods we want to obtain selective information on the type and the equilibria of the doped states in the organic structure. Thus the conduction mechanisms of such composites can be interpreted.
