Modular polymer-based architectures for light absorption and directional charge transport
Polymer-based photoredox-active architectures represent an exciting class of materials for the conversion of sun light into electricity or chemical bond energy, e.g., in photovoltaic or photocatalytic cells. These materials consist of a photosensitizer for light absorption, e.g., a Ru(II) polypyridyl complex, as well as electron donor and acceptor sites for the charge separation and charge transport. In this thesis, the synthesis of redox-active and conjugated telechelic electron acceptor and donor polymers was studied. Moreover, the modular assembly of these polymers to photoredox-active dyads and triads was elucidated. Steady state and transient spectroscopic measurements of architectures revealed the light-induced charge separation.
