Hierarchical Self-organisation of Cyclic Chromophore Arrays for Artificial Light Harvesting
Project management at the University of Würzburg:
In the light-harvesting system of purple bacteria hundreds of chromophores are hierarchically organized in cyclic arrays within a 2D membrane. In this project, we aim to constract a similar, but artificial system based on perylene bisimide dyes that are first organized in trimers to obtain metallacycles containing three perylene bisimides and up to twelve additional antenna dyes. The optical and photophysical properties of these supramolecular dye assemblies are investigated by UV/Vis and fluorescence spectroscopy and, in particular, by single molecule spectroscopy. In the subsequent step, these trimeric units are self-assembled on surfaces to give 2D pattern of interacting multichromophoric subunits.
