The reversible, solvent-dependet folding/unfolding-behavior was used to study the ground and excited states properties of folda-dimer and folda-trimer by means of different spectroscopic methods as well as theoretical studies. The switching between charge transfer or excimer formation pathways of photoexcited molecules influenced by the spatial arrangement of chromophores within defined dye systems illustrates the impact of conformational preferences on functional properties.}, subject = {Perylenbisdicarboximide }, language = {en} } @phdthesis{Rehm2015, author = {Rehm, Stefanie}, title = {Spermine-functionalized Perylene Bisimide Dyes: Synthesis and Self-assembly in Water}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-123201}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2015}, abstract = {The main objective of this thesis was the design and synthesis of perylene bisimide dyes with sufficient water-solubility for the construction of self-assembled architectures in aqueous solutions. Beside these tasks another goal of this project was the control over the self-assembly process in terms of aggregate size and helicity, respectively. Within this thesis an appropriate synthesis for spermine-functionalized perylene bisimide dyes was developed and conducted successfully. The characterization of these building blocks and their course of self-assembly were investigated by NMR, UV/Vis and fluorescence spectroscopy as well as by atomic force and transmission electron microscopy. For the better understanding of the experimental results theoretical calculations were performed.}, subject = {Perylenderivate}, language = {en} }
