Texte intégralThe goal of this project is to develop theoretical models to allow the study of long-range energy transfers in self-assembled biological systems. We will focus on phenanthrene/pyrene π-stacks embedded in a DNA scaffold. The choice of these specific systems is motivated by recent time-resolved spectroscopic experiments, which revealed the important role of the excitonic transfer mechanism. Phenanthrene-based π stacks have demonstrated an exceptional capacity for coherent excitonic transport up to 150nm. At this scale, the transport is due to a mixed mechanism : on the one hand to the delocalization of the exciton on several phenanthrene units, and on the other hand to incoherent jumps between neighboring units. The addition of a pyrene unit also allows the construction of a donor-acceptor system, whose terminal pyrene unit is quenched by nanosecond-scale fluorescence and the photo-excitation leading the system out of equilibrium, exciton transport and fluorescence processes are in competition with the energy relaxation. A preliminary study was carried out on the smallest model produced experimentally, a dimer of phenanthrene and pyrene, characterizing an end of an experimental chain. Temporal competition between photo-induced processes was evaluated by a dynamic study. It allowed the simulation of time-resolved fluorescence spectra, related to the dynamics observed experimentally. Then, theoretical observations were corroborated by experimental hypotheses. At short times after the excitation of a phenanthrene, processes of anti-Kasha and Kasha fluorescence on it were put forward. At longer time scales, a decrease in the population of phenanthrene was observed in favor of the population of pyrene. A strong Kasha fluorescence signal was observed for this fragment. On the other hand, the limits of the model were questioned. Indeed, the experiment poses the hypothesis of a delocalized and coherent behavior at the level of the pyrene. However, it is a local and incoherent mechanism that dominates theoretical observations at the end of the chain. In order to facilitate the interpretation of coherent mechanisms in larger systems, the search for a local characterization of the excitations was carried out. A diabatization method from delocalized electronic states has then been developed. A localization measure has been developed, reporting the effectiveness of the method. To complete the local description of the effect of vibronic couplings, a perturbative study made it possible to determine the dominant vibrations in the vibrational relaxation within the system. Skeletal vibrations of all the atoms of the same fragment showed an important contribution to the acceleration of the dissipation towards the ground state. These were coupled to the local electronic degrees of freedom in order to complete the local vibronic basis. An excitonic Hamiltonian was then parameterized and composed of blocks in this local and minimal basis suitable for the description of intramolecular and intermolecular transitions. The study of reduced stacks of phenanthrenes and pyrenes has made it possible to create a theoretical model for the study of energy transfer in chain polymers. Its efficiency and its relevance have been tested with calculations of coherent dynamics of excitons in a local vibronic base. It includes the preliminary tools for the study of exciton dynamics in extended stacks. In particular, the excitonic description of the Hamiltonian facilitates its extension on a longer scale. This can also be introduced into a more realistic study of dissipative quantum dynamics. It allows to include various effects leading to decoherence and energy loss, likely to impact energy transfers
