The aim of this thesis was to synthesize new asymmetric pi-conjugated A-B systems, which are able to self-assemble in chiral suprastructures due to the presence of a single amino acid and to investigate them with respect to their self-assembling behaviour in solution and in the solid state. The self-assembly process of the synthesized oligothiophenes was investigated in solution by UV/Vis, fluorescence, and CD-spectroscopy. The optical and chiroptical properties pointed out to the formation of aggregates in which the pi-conjugated systems interact with each other confirming the influence of the proline scaffold. Additionally, investigation of the self-assembly properties in the solid state was performed by AFM and TEM: the formation of micelles was observed.
