Energy transport is a key process at play in natural photosynthesis. Although pivotal to biology, this mechanism is still incompletely understood, but drives the interests of both fundamental and applied science. This internship aims at increasing the understanding of artificial photosynthesis by performing a theoretical modeling of EE transport in organic, bio-inspired light harvesting (LH) systems. The model design and parametrization will be guided by time-resolved fluorescence spectroscopy experiments performed in IPCMS. The goal will be to compute quantitatively and to simulate (i) the fluorescence anisotropy decay, which reveals the time scale for the ultrafast individual EE hopping events and (ii) the slower EE diffusion mechanism with a diffusion constant D that is extracted from the fluorescence quenching. This will be a first step towards a better understanding of EE transport, which is necessary to stimulate the emergence of innovative biomimetic photosynthetic materials. The candidate will join the IPCMS and work with J. Léonard performing the EE transport experiments and R. Avriller & B. Bacq-Labreuil working on the theory and simulation of EE transport. The candidate will benefit from a stimulating scientific environment in close connection between theory and experiments.
