Structure and Properties of Nanostructures from Polyelectrolytes and Porphyrins: Self-Assembly in Aqueous Solution Dissertation zur Erlangung des Grades „Doktor der Naturwissenschaften” im Promotionsfach Chemie am Fachbereich Chemie, Pharmazie und Geowissenschaften der Johannes Gutenberg-Universität in Mainz Christian Ruthard geboren in Mainz Mainz, 2010 ii D77 (Dissertation Universität Mainz) iii iv Für Annika v vi Abstract ABSTRACT In this work self-assembling model systems in aqueous solution were studied. The systems contained charged polymers, polyelectrolytes, that were combined with oppositely charged counterions to build up supramolecular structures. With imaging, scattering and spectroscopic techniques it was investigated how the structure of building units influences the structure of their assemblies. Polyelectrolytes with different chemical structure, molecular weight and morphology were investigated. In addition to linear polyelectrolytes, semi-flexible cylindrical bottle-brush polymers that possess a defined cross-section and a relatively high persistence along the backbone were studied. The polyelectrolytes were combined with structural organic counterions having charge numbers one to four.
